if a 117-mile trip took 6 1/2 gallons of gas, how many miles can be driven with a full tank of 15 gallons?
third question
The pitch of a roof is the ratio of the rise to the half-span. if a roof has a rise of 9 feet and a span of 90 feet, what is the pitch?

the ratio of miles to gallons is 162 / 13.5
simplify this by dividing 162 by 13.5 to get 12 miles per gallon.

117 / 6.5 = 18 miles per gallon * 15 = 270 miles.

half span is 45 feet.
ratio of rise to half span is 9 / 45 = 1/5.
the pitch is equal to 1/5.
