Patrice's car gets 30 miles per gallon.

Patrice went on a vacation and used 28.2 gallons of gas for the trip. Patrice rode a bike or the bus after reaching the vacation location, so the car was only used for the drive there and back. How far away was Patrice's destination?

You have two numbers. Do you think you should

add?
subtract?
multiply?
divide?

I'll be glad to check your answer.
