Question

A train of 150 in length is going toward North direction at the speed of 10m/s, a parrot flys at speed of 5m/s toward South direction parallel to the railway track,
find the time taken by the parrot to cross the train

Answer 1

distance = 150

velocity of train =10m/s

velocity of parrot=5m/s

so

net velocity =velocity of train - velocity of parrot =10-5=5m/s

now t=v/s

t=5/150=0.1
