Answer:
It will travel 800 m before coming to rest.
Explanation:
The train comes to 48km/hr. from 96 km/hr in 800m when brakes are applied.
So, the speed decreases by (96-48)=48km/hr. in 800m.
For coming to rest it has to be at the speed of 0km/hr.
To come to this speed the speed has to be decreased is (48-0)=48km/hr.
In the mathematical language,
48:800::48:x
or, 48/800=48/x
or,48x=800×48
or,x = 800×48/48=800
Therefore, it will travel 800 m before coming to rest.
