Question

A train of length 150m is going towards the North at a speed of 10m/s .A parrot flies at a speed of 5m/s towards the south parallel to the railway track . Find the time taken by the parrot to cross the train.

Answer 1

Answer:

the length of the train = 150m

the speed of the train = 10m/s

the speed of the train at 1m/s= 10/150 =1/15

the speed of 5m/s= 1/5*5=5/5=1m/s

Answer 2

Answer:

the bird takes 10 seconds

Explanation:

u=10j

bird velocity =5j

vtp=5j

hence s =150m

time =s/ut*p

150/15

t=10 s
