Answer:
360 km.
Step-by-step explanation:
Speed of the mail train = 30 km/h
given that,
the express train runs 10 km/h faster than the mail train.
Speed of the express train = 30 + 10
= 40 km/h
Time taken by express train = x
Time taken by mail train = x + 3 hrs.
Distance = Speed*Time
=> 40*X = 30*(x + 3)
=> 40x = 30x + 90
=> 40x - 30x = 90
=> 10x = 90
=> x = 9
Therefore, distance = 40*9
= 360 km.
