HERE IS YOUR ANSWER
(i) Let the distance travelled in km in 20 mins be x
Distance travell in km 75 x
Time taken in mins 60 20
1 Hour = 60 min
Now,x = 75×20/60
we get= 25km
so,In 20mins the trains covers 25km.
(ii) Let time taken in mins to cover 250km be x.
Distance travell in km 75 250
Time taken in mins 60 x
Now,x = 250×60/75
we get= 200 mins or 3 hour 20 mins
Therefore, 3hours 20 mins will be required to cover a distance of 250kilometre.
