Question
Select the correct answerTwo cars A and B start simultaneously from two different places and travels towards each other. They arrive at their destination after 2 hrs and 3 hrs respectively. If speed of car A is 48 km/hr. what is the speed of car B?Options36 km/hr.40 km/hr.32 km/hr.48 km/hr.
Solution 1
To solve this problem, we need to understand that the distance each car travels is equal to its speed multiplied by the time it travels. Since the two cars are traveling towards each other, the total distance they cover is the same.
Step 1: Calculate the distance covered by car A. The speed of car A is given as 48 km
Solution 2
To solve this problem, we need to understand that the distance each car travels is equal to its speed multiplied by the time it travels. Since the two cars are traveling towards each other, the total distance they cover is the sum of the distances each car travels.
Step 1: Calculate the distance car A travels. The speed of car A is given as 48 km/hr and it travels for 2 hours. Therefore, the distance car A travels is 48 km/hr * 2 hr = 96 km.
Step 2: Calculate the speed of car B. We know that car B travels for 3 hours and covers the same distance as car A (96 km). Therefore, the speed of car B is the distance it travels divided by the time it travels, which is 96 km / 3 hr = 32 km/hr.
So, the speed of car B is 32 km/hr. The correct answer is 32 km/hr.
