Question 709489:
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 99-meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time?
You can put this solution on YOUR website! D=RT
D=8T
D-99=2T
OR D=2T+99
8T=2T+99
8T-2T+99
6T=99
T=99/6
T=16.5 SECONDS THEY WILL MEET.
PROOF:
D=8*16.5=132 m.
D-99=2*16.5
D=99+33=132 m.
