c. If Laura starts 11.1 metres behind Joe, who will win, and by how much?
d.How far behind Joe does Laura have to start for the race to be a dead heat?
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Joe runs x m/min
Laura runs 10/9 m/min, since she runs 100 meters when Joe runs 90.
If Joe runs 100 meters, Laura runs (100*10/9)=1000/9 m or 111.1 meters.
a. She will beat him by 1.1 meters
b. She will win by 0.1 meter.
c. This will be a dead heat to the nearest tenth of a meter.
d. To be more accurate, 11.1111111m
