Question

Molly can drive her car 112 miles on 4 gallons of gas and 182 miles on 6.5 gallons write an equation that represented between g the number of gallons she has in her car and m the number of miles she can drive then use the equation to find how many gallons she would need to drive 420 miles

Answer 1

Explanation:

Answer 2

112g=4m
182g=6.5m
Hence,
70/2.5 g=m
m = 28g
if m = 420 mi
g = m/28 = 420/28 = 15 gallons.
