Question

The speed of B is 20% more than the speed of A. If A covers distance in 20 minutes then B will cover that distance

Answer 1

s=d/t

let distance be x

speed of a =x/20

speed of b is 20 percent more than a

speed of b= 20/100 X x/20 + x/ 20

= 3x/50

3x/50=x/t

t =50/3 minutes

16.667 minutes
