Question

A certain distance is covered in a certain time .If 40% more distance had to cover in 37% less time then what will be the ratio of speed in both situation​

Answer 1

Step-by-step explanation:

Explanation:

Let distance = x km and usual rate = y kmph.

Then, x - x = 40 2y(y + 3) = 9x ....(i)

y y + 3 60

And, x - x = 40 y(y - 2) = 3x ....(ii)

y -2 y 60

On dividing (i) by (ii), we get: x = 40.
