Question

in a certain distance is covered at a certain speed if half the distance is covered in double time ,then what is the ratio of two speeds

Answer 1

Answer:

A certain distance is covered at a certain speed. If half of this distance is covered in double the time, the ratio of the two speeds is. 4 : 1. 1 : 4.

Step-by-step explanation:

Answer 2

Let the distance(S) covered in speed(V) be x.
V=S/t
V=x/t
Case 2,
Half of distance=x/2, double time 2t,
V1=x/2/2t
V1=x/4t

We should find
V:V1=x/t:x/4t
V:V1=4:1
