Question

In covering a distance of 30 km, Abhay takes 2 hours more than Sameer. If Abhay doubles his speed, then he would take 1 hour less than Sameer. Abhay's speed is:

Answer 1

Hola !

 Abhay's speed  =  x km/hr

So,

30/x - 30/2x = 3

60/2x - 30/2x = 3

30/2x = 3

6x = 30

 x = 5 km/hr.

Answer 2

Abhay's speed is: 5 km/h.

Let Abhay's speed be x km/hr.

Then,30/x-30/2x= 3
 
          6x = 30

          x = 5 km/hr.
