With a full tank of gas,

Question

With a full tank of gas, you can drive 500 miles and your car can go 18 miles per gallon.

Write an equation to model this situation (use m for miles you can drive and g for gallons in the tank).

Answer 1

500 miles on a full tank with 18mpg

18g= 500

g=500/18 = 250/9 = 27 7/9 gallons in a full tank

g = m/18

m = 18g

miles = mpg times gallons

it's similar to distance = rate of speed times time

d=rt

distance = rate of miles per gallon times gallons

m= m/g x g
