Question

Two friends who live 48 miles apart, left their houses at the same time and started to run towards each other at the rates of 5 mph and 7 mph. How much closer to each other will they be in one hour? How soon will they meet?

Answer 1

If they run one at 5mph and the other 7mph, in an hour they will be 36mi apart, 12mi closer.

Kid one runs 20mi in 4 hours

Kid two rubs 28mi in 4hours

They meet after four hours running from the start.

Or 3 hours running after being 36mi apart in letter a.

Hope it helped!
