10. A train of 150 m length is going gowards north direction at a speed of 10 m s-1. A parrot flying at the speed of S, m s 1towards south direction parallel to the railway track. The time taken by the parrot to cross the train is equal toA) 15 sB) 12 s10 sD) 8 s

Answer»

Since the parrot and the train are moving in the opposite direction

therefore parrot's relative velocity will be 5m/s + 10 m/s =15m/s

distance=speed*time

so 150=15*t

t=150/15 =10 sec
