A train of 150 m length is going towards North at a speed of 10 m/s. A bird is flying at 5 m/s parallel to the track towards South. The time taken by the bird to corss the train is

A

`12` sec

B

`8` sec

C

`15` sec.

D

`10` sec.

Text Solution

Verified by Experts

The correct Answer is:
D

`V_(PT)=5-(-10)=15` and `S_(PT)=150` m
`t=(S_(PT))/(V_(PT))=(150)/(15)=10` sec.
