A certain distance is covered by a cyclist at a certain speed. I a jogger covers half the distance in double the time, the ratio of the speed of the jogger to that of the cyclist is:  Choices
A) 1:2  B) 2:1  C) 1:4  D) 4:1  E) None of these
let the distance covered by the cyclist be x and the time taken be y. Then, Required ratio=1/2x/2y:x/y=1/4:1=1:4.   1:4orrect Option: 1:4
