Question

Tracy is running a trail in Hanna park she can run 1 mile in 10 minutes Yanni is running the same trail as Tracy Johnny can run a mile in five minutes but starts running 20 minutes after Tracy started on the trail if they started the trail from the same point how long will it take Yanni to catch Tracy

Answer 1

It will take Yanni 20 minutes to catch up with Tracy. This can be determined with the fact that average velocity equals change in distance divided by change in time. Rearrange the equation so that we are solving for the final time, then set Tracy's equation equal to Yanni's equation and solve for the final time.
