Answer:
3.5 miles
Explanation:
Lydia:
3 gallons of gas = 114 miles
We want to know how many miles a friend can travel on one gallon of gas, so we divide both sides by 3
1 gallon of gas = 114/3 miles = 38 miles
Lucy:
One point is
10x corresponds to 415y
10 gallons = 415 miles
divide both sides by 10 to get one gallon on a side
1 gallon = 41.5 miles
Lydia:
38 miles = 1 gallon
Lucy:
41.5 miles = 1 gallon
For 1 gallon, the difference is 3.5 miles, with Lydia having 3.5 miles less than Lucy.
