Question

A train travels 300 km with the uniform speed the speed of the train is increased by 5 kilometre per hour it takes 48 minutes less to cover the same distance find initial speed of the train​

Answer 1

Let the spees of the train be v and the distance which have to cover be x and time taken be t

.

Given

x=300km

In first case train have to cover 300km in the hours.

speed the train,(v) = 300/t..............(1)

In second case ,

speed had been 5km/h more, then it would have taken 2 hours less to cover the same distance.

so speed= v+5

time = t-2 hours.

So ,

speed of train ,

v+5 = 300/(t-2).........................(2).

see picture!

speed of train=25 km/hr.

please mark it as brainlist answer.
