Answer 1

Hope you will understand

Answer 2

Hey mate!

Here's your answer!!

We know that,
Average velocity=initial velocity+final velocity/2

The initial velocity of the train=60m/s.

The final velocity of the train=40m/s.

Average velocity

= u+v / 2

= 60meter per sec+40 meter per sec/2

= 100/2

= 50 m/s

Hope it helps you!
