Walking at three-fourth of his usual speed, a man covers

Walking at three-fourth of his usual speed, a man covers a certain distance in 2 hours more than the time he takes to cover the distance at his usual speed. The time taken by him to cover the distance with his usual speed is

4	×usual time – usual time = 2
3

⇒	1	usual time = 2
	3

∴ Usual time = 2 × 3 = 6 hours
Second Method :

Here,	A	=	3	, time= 2 hrs.
	B		4

Usual time =	A	× time
	Diff. of A and B

=	3	× 2 = 6 hours
	(4 − 3)
