Question

A train is moving at a uniform speed of 75 km/hour.(i)             How far will it travel in 20 minutes?(ii)            Find the time required to cover a distance of 250 km.

Answer 1

`75km/hr = (75km)/ (60 min)`
`1 hr = 60 min`
(i) it will travel =`x` km
`x/20 = 75/60`
`x = (75*20)/60 = 25km`
(ii) time taken = `t `min
`250/t = 75/60`
`t = (250*60)/75`
`= 200` mins
`= 3 hrs20 min`
