If a car can travel 340 miles on 14gallons of gas ,then how many more gallons are needed for this car to travel 544miles ?(usr proportions)

Answer 1

conversion factor is
(14 gal/340 mi)

(14 gal/340 mi)(544 mi) = 22.4 needed for whole trip
so
22.4-14 = 8.4 more needed
=============================
with proportions (I do physics not math so not my thing)
14/340 = x/544
so
x = (14/340)544 again
