Question 945183: two persons are to run a race, but one can run 8 meters per second, whereas the other can run 2 meters per second. If the slower runner has a 81 meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = the distance in meters the faster runner travels
until the slower runner is caught
Let = time in seconds for faster runner to
catch slower runner
-----------------------
faster runner's equation:
slower runner's equation:
-----------------
By substitution:
In 13.5 seconds the faster runner catches
the slower runner
