Speed =80km/hr
=80*1000/60*60
=80*5/18
=400/18
=200/9m/s
This means in 1s it covers 200/9meters
In 15 minutes it will cover:200/9*15*60
=5*20*200
=20000metres
=20km
Hope its helpful
I could have done like this:-
15m=1/4th of an hour.
The train covers 80 km in 1hr so
it covers 80/4=20 kms in 15 min.
That was easy.
Glad to help you.
