Lets find the unit rate of both of the shirts.
5 for 63
4 for 54
63/5 = 12.60
54/4 = 13.50
Now we have our unit rates!
Greg = $12.60 per shirt
Zachary = $13.50 per shirt
Greg's shirt were cheaper than his brothers, so it has a better cost.
To find miles per hour you divide the number of miles by the number of hours
(7 1/2)/(3/8) = (15/2)(8/3) = 20 mph
