- Let speed of train be X kilometre per hour.
- Time taken to travel 480 km= 480/X hrs
In second condition,
- Speed of train= (X-8) km/h
It is also given that rain will take 3 hours to cover the same distance,
- Therefore, time taken to travel 480 kilometre per hour= (480/x+3)hrs
As we know that,
Distance= Speed× Time
(x-8)(480x+3)=480
See calculations in attachment (:
