How much farther can Arianna's car travel on one gallon of gas than Bo's car?
Answer
Attempt 1 out of 2

Answer 1

Arianna's rate = 104.4 ÷ 4 = 26.1 miles per gallon (also 261 ÷ 10, 313.2 ÷ 12, etc.).
Bo's rate = 41.4 ÷ 2 = 20.7 miles per gallon.
Difference = 26.1 − 20.7 = 5.4 miles per gallon.

Arianna can travel 5.4 miles farther on one gallon than Bo.
