Question

Find both unit rates. 250 miles on 8 gallons of fuel. A. 32 miles per gallon and 0.3125 gallons per mile B. 31.25 miles per gallon and 0.032 gallons per mile C. 250 miles per gallon and 8 gallons per mile D. 0.032 miles per gallon and 31.25 gallons per mile

Answer 1

The rate is either distance over mass or mass over distance. So simply divide.

250 miles / 8 gallons = 31.25 miles per gallon
and
8 gallons and 250 miles = 0.032 gallons per mile

So the answer is B.
