Question

You and your friend are having a race, but since you are faster than him, you decide to give him a head start. He starts 12ft in front of the starting line while you start on the starting line. You run at 10ft per second, while your friend runs at 9ft per second. after how many seconds will you and your friend be same distance from the starting line?

Answer 1

Set up two equations to better understand the values and variables given.

You: y=10s
Friend: y=9s+12

Then, set them equal to each other to find when the values are the same/

10s=9s+12
10s-9s=12
s=12

After 12 seconds, you and your friend will be the same distance from the starting line.
