60 miles per hour and 55 miles per hour it will be 240 miles over 4 hours because if you divide 240 by 4 it is 60 miles faster than the other which is 55 miles per hour.

240 miles over 4 hours is faster than 330 miles over 6 hours. When you find the unit rate there is a difference of 5 between 60 and 55.
