Question

suppose a car uses 60 gallons of gasoline for a trip of 600 miles. how many gallons would be used on a trip of 100 miles

Answer 1

Well, first. A trip of 100 miles in 1/6 less than the 600 mile trip. So, we also know that a 600 mile trip uses 60 gallons. In order to find the amount used in a 100 mile trip, just divide 60 gallons by 6!

60 / 6 = 10

Which means, that in a trip of 100 miles. 10 gallons of fuel are used!
