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 :
(a)1 : 2
(b)2 : 1
(c)1 : 4
(d)4 : 1
Answer
Answer (as printed): C
Explanation
Let the distance covered by the cyclist be $x$ and the time taken be $y$. Then, $$\text { Required ratio }=\frac{\frac{1}{2} x}{2 y}: \frac{x}{y}=\frac{1}{4}: 1=1: 4 \text {. }$$
