A man walks at the speed of 4 km per hour from point A to B and at the speed of 8km per hour from point B to A
what is the ratio between the time taken by the man from point A to B and B to A?
:
let d = distance from A to B
Write a time equation; time = dist/speed
d%2F4 + d%2F8 = total time
common denominators
%282d%29%2F8 + d%2F8 = total time
therefore
The ratio of the time there to time back: 2:1
