Question

Allen’s boat used 6 gallons of gas in 5 hours. At this rate, how many gallons of gas will the boat use in 12 hours?
a.
10 gallons
c.
9.6 gallons
b.
14 gallons
d.
14.4 gallons

Answer 1

set up a proportion...
6/5 = x/12 (6 gallons in 5 hrs = x gallons in 12 hrs)
cross multiply
(5)(x) = (6)(12)
5x = 72 -- divide both sides by 5
x = 72/5
x = 14 2/5 gallons or 14.4 gallons

any questions ?
