Step-by-step explanation:
a) Speed of train =75km/h
It means it covers 75 km in one hour.
Therefore
1hr = 75km
60min = 75 km (1h = 60 min)
Divide both side by 3 we get
60/3 = 75/3
20 = 25
It coverd 25 km in 20 minutes..
b) now we have to find time to cover 250 km.
1h = 75km
3h = 75×3
3h = 225
It shows that it take 3hr to cover 225km
But we have to find time for 250km.
25 km coverd in 20 minutes. (done in part (a))
Therefore it take 3h 20 minutes to cover 250km.
