Question

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 1

The correct option is C $1:4$

Let the distance covered by cyclist is '2x' m and time 't' sec

Then the distance covered by jogger is 'x' m and time is '2t' sec

Now the ration of the speed of the jogger:speed of the cyclist

$\frac{s_1}{s_2}=\frac{\frac{x}{2t}}{\frac{2x}{t}}=\frac{1}{4}$

Then $s_1:s_2=1:4$
