The fuel tank in Mr. Swenson's car holds 16.5 gallons of fuel.

The car consumes 1 gallon of fuel for each 24.3 miles driven.

Mr. Swenson started a trip of 250 miles with a full tank of fuel.

Abouthow much fuel remained at the end of the trip?

Given:

Fuel tank : 16.5 gallons of fuel

1 gallon = 24.3 miles

250 miles traveled

250 miles / 24.3 miles = 10.29

10.29 * 1 gallon = 10.29 gallons

16.5 gallons - 10.29 gallons = 6.21 gallons of fuel remaining.

16.5 gallons * 24.3 miles = 400.95 miles

400.95 miles - 250 miles = 150.95 miles

150.95 miles / 24.3 miles = 6.21 gallons of fuel remaining
