Question

How much miles will the car use with 17 gallons of gas?

Answer 1

From the graph you can see you use 5 gallons per mile so if you do 5 times 3 it equals to 15

Answer 2

from the graph we can see that

for 2 gallones - it can travell 70 miles

4 gallones - 140 miles

we will take the first case

2 gallones - 70 miles

17 gallones - ? miles

cross multiply

`(17 * 70)/(2)`

= 595 miles
