Question
Vehicle ‘M’ is ahead of vehicle ‘N’ by 250
metres and is moving at 24 m/s. Vehicle ‘N’ is travelling at 90 km/h. If both are moving in the same direction, find the time taken by vehicle ‘N’ to catch up with vehicle ‘M’.Solution
Speed of vehicle ‘N’ = 90 ÷ 3.6 = 25 m/s
So, relative speed of vehicle ‘N’ with respect to vehicle ‘M’ = 25 – 24 = 1 m/s
So, time taken by vehicle ‘N’ to catch up = 250 ÷ 1 = 250 seconds
