A certain distance is covered by a cyclist at a certain speed. If a jogger covers half the distance in double the time, the ratio of the speed of the jogger to that of the cyclist is

1. 1 : 4
2. 4 : 1
3. 1 : 2
4. 2 : 1

Correct Option: A

Let speed of cyclist = x kmph
& Time = t hours

Distance =	xt	while time = 2t
	2

∴ Required ratio =	xt	: x
	2 × 2t

= 1 : 4
