Billy and his younger brother, Reggie, are going to race each other to the park. They will start running at the same time, but Billy is letting Reggie start 20 meters ahead. Billy can run 8 meters per second, and Reggie can run 6 meters per second.
Which equation can you use to find s, the number of seconds it will take for Billy to catch up to Reggie if they each run as fast as they can?
A.
20s + 6 = 8s
B.
20 + 6s = 8s
The correct equation is:
A. 20s + 6 = 8s
This equation accounts for the fact that Billy needs to cover a distance of 20 meters to catch up to Reggie, and that both are running at their respective speeds.
the answer is b
Apologies for the confusion. Let's go through the equation to verify:
20 + 6s = 8s
Subtract 6s from both sides:
20 = 2s
Divide by 2:
s = 10
This means it will take Billy 10 seconds to catch up to Reggie. Thank you for pointing out the correct answer!
