Answer 1

Well, if it takes 4 gallons to go 100 miles...how many miles would you go with just 1 gallon?

Answer 2

50?

Answer 3

Not quite...it makes sense that if you go 100 miles....on 4 gallons of gas...then you effectively went

\[\large \frac{100miles}{4 gallons} = 25\frac{miles}{gallon}\] right?

Answer 4

oh

Answer 5

So knowing that with 1 gallon of gas...you can go 25 miles...

how many gallons would it take to go 150 miles?

Answer 6

6

Answer 7
