Time and Distance Q.6

6The two trains of respective lengths 160 m and 200 m travel at the speeds of 48 m per second and 52 m per second respectively in opposite direction to each other. What is the total time taken by them to cross each other?

Option : A
Explanation : Relative speed = 48 + 52 = 100 m/s
Total distance covered by both the trains = 160 + 200 = 360 m
Speed = Distance/Time
∴ 100 = 360/Time
∴ Time = 3.6 seconds
