Question

Julie is making a trip by car. Julie knows that her car gets 32 miles per gallon, and holds ten gallons of gasoline. If Julie has `1/4` of a tank of gas left, how many more miles can she travel before she needs to refuel?

Answer 1

`80` miles

Explanation:

Julie's car can hold `10` gallons of gasoline.

The tank has `frac(1)(4)` of gas left.

That means the car has `10 times frac(1)(4) = 2.5` gallons of gas left.

Her car gets `32` miles per gallon of gasoline.

Now, the car has `2.5` gallons of gas left, so it can run for another `32 times 2.5 = 80` miles, before needing a refuel.
