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