Answer: 16 miles 
Step-by-step explanation:
The car used 1/64 gallons to travel 1/4 miles. To find out how many miles the car can travel using 1 gallon, use direct proportion:
1/64 gallons            :              1/4 miles 
1 gallon                   :                  x miles 
Cross multiply:
1/64x = 1/4 
x = 1/4 ÷ 1/64
= 1/4 * 64/1
= 16 miles 
On one gallon of gas, the car can travel 16 miles.
