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
