Question
A car is moving ata constant speed of40 km/hr along astraight road which heads towards a large vertical wall andmake a sharp 90° turn by the side of the wall. A fly flying ataconstant speed of 100 km/hr, starts from the wall towards thecaratan instant when the caris20km away, flies until it reachesthe glasspane of the car and returns to the wall at the samespeed. It continues to fly between the car and the wall till thecar makes the 90° turn, (a) What is the total distance the fly hastraveled during this period ? (b) How many trips has it madebetween the car and the wal
Solution
The first step to solve this problem is to determine how long the car takes to reach the wall. Since the car is moving at a constant speed of 40 km/hr and the wall is 20 km away, the car will take 20 km / 40 km/hr = 0.5 hours to reach the wall.
The fly is flying at a constant speed of 100 km/hr. Since the fly starts flying when the car starts moving and stops when the car reaches the wall, the fly is flying for the same amount of time as the car, which is 0.5 hours.
The total distance the fly travels is its speed multiplied by the time it is flying. So, the fly travels 100 km/hr * 0.5 hr = 50 km.
To determine how many trips the fly has made between the car and the wall, we need to know the distance between the car and the wall. However, this information is not provided in the problem. Therefore, we cannot determine the number of trips the fly has made.

Jatin and Sonia are driving towards each other on a straight road. Jatin drives at a constant speed of 80 kilometres per hour, while Sonia drives at a constant speed of 60 kilometres per hour. They start from locations that are 200 kilometres apart. A bird sitting on Jatin's car starts flying towards Sonia's car once they start driving and continues to fly back and forth between the cars until they meet. If the bird flies at a constant speed of 90 kilometres per hour, how far does the bird fly before Jatin and Sonia meet?
Two cars, each having speeds of 𝑣! = 40.0 "# , and 𝑣$ = 35.0 "# are headed at each other on the same straightroad. A bird that can fly 𝑣% = 68.0 "# flies off the front of one car when they are 𝐷 = 60𝑚 apart and headsdirectly for the other car. On reaching the other car the bird flies back to the first car and repeats this processuntil it can’t. What is the total distance the bird travels before the cars collide
