Billy and his younger brother Reggie are going to raise each other to the park they will start running at the same time but Billy is letting Reggie start 20 m ahead Billy can run 8 mph per second and Reggie can run six meters per second which equation can be used to find s the number of seconds it will take for ability to catch up to Reggie if they eat run as fast as they can

Answer 1

Let s be the number of seconds it will take for Billy to catch up to Reggie.

Therefore, the distance Billy runs in s seconds is 8s and the distance Reggie runs in s seconds is 6s.

Since Reggie starts 20 meters ahead, the distance Billy must run to catch up to Reggie is 20 meters less than the distance Reggie runs:

8s = 6s + 20

Subtracting 6s from both sides:

2s = 20

Therefore, s = 10 seconds.

So, it will take Billy 10 seconds to catch up to Reggie.
