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.

Explanation

`75(km)/(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`
