It costs 25 in gas to drive to my parents house If gas costs

It costs $25 in gas to drive to my parents\' house. If gas costs $2.89 per gallon and my car gets 15 miles per gallon, how far is it from my house to my parents\' house?

Solution

Total amount of gas used = total cost / cost per gallon
= 25/2.89
= 8.6505 gallon

distance = distance per gallon * Total amount of gas used
= 15 * 8.6505
= 129.8 miles
Answer: 129.8 miles
