Solution
Here is a Python program that fulfills the requirements:
class Vehicle:
def __init__(self, distance, time):
self.distance = float(distance)
self.time = float(time)
class Car(Vehicle):
def __init__(self, distance, time):
Vehicle.__init__(self, distance, time)
def calculate_speed(self):
speed = self.distance / self.time
return speed
# Input distance and time
distance, time = input().split()
car = Car(distance, time)
# Calculate and print speed
speed = car.calculate_speed()
print("Speed of car: {:.5f} km/hr".format(speed))
This program first defines a base class Vehicle that takes distance and time as inputs and stores them as float values. Then it defines a derived class Car that inherits from Vehicle and adds a method to calculate speed. The speed is calculated by dividing distance by time. The program then takes user input for distance and time, creates a Car object with these values, calculates the speed, and prints it. The speed is printed with 5 decimal places as per the output format in the question.

Problem StatementKaniska is tasked with creating a program that allows users to input information about different types of vehicles and calculate the time it takes for these vehicles to travel a given distance at their maximum speeds. The program will support three types of vehicles: Cars, Bicycles, and Boats.Your task is to implement the Vehicle class as the base class for these three vehicle types. The Vehicle class should have the following properties and functionalities:Properties:numOfWheels (integer): representing the number of wheels of the vehicle.maxSpeed (floating-point): representing the maximum speed of the vehicle.Functionalities:A default constructor to initialize numOfWheels and maxSpeed to 0.A virtual function setNumOfWheels(int wheels) to set the number of wheels of the vehicle.A virtual function setMaxSpeed(float speed) to set the maximum speed of the vehicle.A virtual function getNumOfWheels() to get the number of wheels on the vehicle.A virtual function getMaxSpeed() to get the maximum speed of the vehicle.A virtual function timeToTravel(float distance) that calculates and returns the time it takes for the vehicle to travel the given distance at its maximum speed.Implement three derived classes, Car, Bicycle, and Boat, which inherit from the Vehicle class. Each derived class should override the timeToTravel(float distance) function with the appropriate calculation for the specific vehicle type. The Car and Bicycle classes should calculate the time based on their maximum speed in mph, while the Boat class should consider the maximum speed in knots and convert it to mph using the formula 1 knot = 1.151 mph.In the main function, create instances of each vehicle type (Car, Bicycle, and Boat) and take user input for the number of wheels and maximum speed for each vehicle. Then, the user will input a distance, and the program will display the details of each vehicle and the time it takes for each vehicle to travel the given distance at its maximum speed.Note: This kind of question will help in clearing Capgemini recruitment.Input format :The first line consists of the number of wheels and the maximum speed of the car, separated by a single space.The third line consists of the number of wheels and the maximum speed of the bicycle, separated by a single space.The fifth line consists of the maximum speed of the boat (in knots).The sixth line consists of the distance to travel (in miles).Output format :The program outputs the details of the car, bicycle, and boat, including the number of wheels and the maximum speed for each vehicle, as well as the time it would take to travel the specified distance at maximum speed.The output includes the vehicle type, number of wheels, maximum speed, and time taken to travel the distance.The time taken is displayed in hours.Refer to the sample input and output for format specifications.Code constraints :The number of wheels (numOfWheels) for each vehicle is a positive integer.The maximum speed (maxSpeed) for each vehicle is a positive floating-point number.The distance to travel is a positive floating-point number.The maximum speed of the Boat (in knots) should be converted to mph using the formula: 1 knot = 1.151 mph.Sample test cases :Input 1 :4 602 153050Output 1 :Vehicle Details:Car has 4 wheels and can go up to 60 mph. It would take 0.833333 hours to travel 50 miles at maximum speed.Bicycle has 2 wheels and can go up to 15 mph.

Mohit wants a financial calculator program for Fixed Deposits and Simple Interest. He needs a program that uses multi-level inheritance. The program should have three classes:class Investment - Holds the principal, interest rate, and time period as attributes.class FixedDeposit - Derived from the Investment class, calculates the maturity amount using a method called calculateMaturityAmount(). class SimpleInterest - Derived from FixedDeposit class, prints the maturity amount using a method called printFD(). It then computes the simple interest and prints it using a method called calculateSimpleInterest().Formulas used:Maturity Amount = P * (1 + (R/100)) ^ T where the power value is calculated using pow() function from the math library.Simple Interest = P * N * R/100where P - principal, R - interest rate, and N - time period in years.Input format :The first line consists of three double-point numbers separated by a space representing the principal amount, interest rate, and time period in years to calculate Fixed Deposit and Simple Interest.Output format :The first line displays "Maturity Amount: " followed by a double value which is the calculated Maturity amount rounded to two decimal places.The second line displays "Simple Interest: " followed by a double value which is the calculated Simple interest rounded to two decimal places.Refer to the sample outputs for the formatting specifications.Code constraints :In this scenario, the test cases fall under the following constraints:1 ≤ Principal amount ≤ 1060.1 ≤ Interest rate ≤ 100.1 ≤ Time period ≤ 10Sample test cases :Input 1 :1000.0 5.0 2Output 1 :Maturity Amount: 1102.50Simple Interest: 100.00Input 2 :1500.0 4.5 4Output 2 :Maturity Amount: 1788.78Simple Interest: 270.00
