(cm/min)      (min)         (cm)
SPEED         TIME         DISTANCE
 18            d/18            d
 16            d/16            d
               25/60

d%2F16-d%2F18=25%2F60

d%2F%282%2A2%2A2%2A2%29-d%2F%282%2A3%2A3%29=25%2F%282%2A2%2A3%2A5%29
lowest denominator to use is 2%5E4%2A3%5E2%2A5

45d-40d=25%2A12
5d=5%2A5%2A12
highlight%28d=60%29cm
