Bryan is taking a road trip to Dallas, Texas. His car can travel 315 miles with 18 gallons of gas. Bryan's s car holds 20 gallons of gas. Suppose Bryan's gas gauge indicates that he has one-fourth tank of gas left, how many more miles can Bryan travel before he runs out of gas?
Accepted Solution
A:
1) Find the unit rate 315÷18=17.5 2) See how many miles he can go on a full tank of gas 17.5×20=350 3) Find how much gas total is in the tank [tex] \frac{20}{4}[/tex] =5 gallons 4) Find how many miles he has left before his tank is empty 17.5×5=87.5
He has 87.5 miles left to go before he runs out of gas.
