    Question

    Vehicle β€˜M’ is ahead of vehicle β€˜N’ by 250

    metres and is moving at 24 m/s. Vehicle β€˜N’ is travelling at 90 km/h. If both are moving in the same direction, find the time taken by vehicle β€˜N’ to catch up with vehicle β€˜M’.
    A 265 secs Correct Answer Incorrect Answer
    B 242 secs Correct Answer Incorrect Answer
    C 230 secs Correct Answer Incorrect Answer
    D 250 secs Correct Answer Incorrect Answer

    Solution

    Speed of vehicle β€˜N’ = 90 Γ· 3.6 = 25 m/s
    So, relative speed of vehicle β€˜N’ with respect to vehicle β€˜M’ = 25 – 24 = 1 m/s
    So, time taken by vehicle β€˜N’ to catch up = 250 Γ· 1 = 250 seconds
