Answer 1

Answer:

 525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon

gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

$distance = \frac{miles}{gallon} (gallons)\\distance = \frac{35 miles}{gallon} (15 gallons) = 525$
