4.
Distance covered by the train = 625 km
Time taken by the train = 7 hours
Speed = distance/time
Therefore, speed of the train = 625/7 km/hr
= 89.285 km/hr
5.
We know that Speed=Distance/Time
85=382.5/Time
Time =382.5/85
Time=4.5 hours
6.
Speed = 630 km/hr
Time = 2.5 hr
Now,
Distance = speed/time
=630/2.5
=252 km
