A car has a mileage rating of 40 miles per gallon of gasoline.

How many miles can the car travel on 60.5 liters of gasoline?

Answer 1

The car can travel 639.3 miles on 60.5 liters of gasoline

Solution:

Given that car has a mileage rating of 40 miles per gallon of gasoline

To find: Number of miles can the car travel on 60.5 liters of gasoline

Let "x" be the number of miles the car travel on 60.5 liters of gasoline

Let us first convert 60.5 liters of gasoline to gallons of gasoline

Use the conversion factor,

1 liter = 0.264172 gallon

60.5 liters = 0.264172 x 60.5 gallon

60.5 liters = 15.98241 gallon

Thus from given statement,

1 gallon of gasoline = 40 miles

15.98241 gallon = x miles

This forms a proportion and we can solve the sum by cross multiplying

`x * 1 = 40 * 15.98241\\\\x = 639.3`

Thus the car can travel 639.3 miles on 60.5 liters of gasoline
