The Honda Civic Hybrid vehicle, powered by gasoline-electric technology, gets 49 miles per gallon in city driving and 51 miles per gallon in highway driving. The car is driven 447 miles on 9 gallon of gasoline. How many miles were driven in the city and how many were driven on the highway?

49 miles/gal = city rate
51 miles/gal = highway rate

447 miles/9 gal is how much you drove...

(city mileage)/(city rate) + (highway mileage)/(highway rate) = 9 gal.

Set up a problem with variables or use a guess-and-check approach.
