Question

David drove 168 miles on 7 gallons of gasoline. Which of the following equations can be used to find how far can he can travel on a full tank of 16 gallons?

Answer 1

7/168 = 16/x
heres the answer

Answer 2

168 miles on 7 gallons.....168/7 = 24 miles per gallon

y = 24x....where y is total distance driven in miles and x is number of gallons

how far can he travel on 16 gallons....sub in 16 for x
y = 24x
y = 24(16)
y = 384 miles
