If a car can travel 250 miles on 10 gallons of fuel, how many gallons are required to travel 1,325 miles?

1325                      250
-------          =        -------      
    x                           10

1325(10) = 250x

13250/250 = 250x/250

x = 53 

53 gallons are required to travel 1325 miles

hope this helps
