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:

5 kmph
6 kmph
6.25 kmph
7.5 kmph

Correct Answer: 5 kmph

Explanation:

Let Abhay's speed be x km/hr.

Then,	30	-	30	= 3
	x		2x

⟹ 6x = 30

⟹ x = 5 km/hr.
