Answer:
16.25
Step-by-step explanation:
Well, the school is 13/2 miles away.
13/2 = 6.5
Since Edward goes by car there and back, he travels 13 miles a day.
6.5 x 2 = 13
He went for 5 days.
5 x 13 = 65
The car consumed 4 gallons of gas by driving those 65 miles.
65 / 4 = 16.25
Therefore, Edward's car gets 16.25 miles per gallon!
