If the speed of the train is increased by 5 km/hr from its normal speed it would have taken 2 hours less to cover 300 kms.
what is its normal speed?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Let x be the normal speed, in .
Then   =   is the time spent for the journey at the speed of x .

Also,   =   is the time spent for the journey at the speed of (x+5) .

We are given that  -  = 2. 

It gives an equation 

 -  = 2.

Solve it for x. The first step is to multiply both sides by x*(x+5).

Answer. 25 .
