How many gallons of gasoline should you expect to use?
Would a car that has only half the gas mileage require twice as much gasoline for the same trip?

Do you know what the first steps would be to solve a problem like this?

Jimenar42 · Answer

I dont know I just did the first one right now I divided 1287/22 = 58.5 and I got it correct but I cant figure out the second question

Astro · Answer

OK, That's a really good start. You already know the first steps so let's look at the second question. What are you confused about? Is it the way it's stated?

Jimenar42 · Answer

I dont know what to do if I should multiply or divide and what numbers because the half the gas mileage is 11 miles per gallon. But I think I am going to divide 1287/11

Vocaloid · Answer

yeah you have the right idea

# of gallons = (total miles/miles per gallon)
