Question

Your car gets 15 miles to the gallon and your friend's car gets 25 miles to the gallon. you decide to go on a road trip to virginia tech, which is 300 miles away. if gas costs $4 per gallon and you decide to split the gas money, how much money will you save in gas by driving your friends car

Answer 1

You will save $32.

Explanation:

Your car gets 15 miles to the gallon and your friend's car gets 25 miles to the gallon.

You decide to go on a road trip to Virginia tech, which is 300 miles away.

Gallons needed for your car =
`(300)/(15)` = 20 gallons

Cost of 20 gallons gas =
`20*4=80` dollars

Gallons needed for friends car =
`(300)/(25)` = 12 gallons

Cost of 12 gallons gas =
`12*4=48` dollars

Hence, while driving friend's car you will save =
`80-48=32` dollars

Therefore, you will save $32.

Answer 2

You would save $32 if you used your friends car.

I found this out by doing this:

300/15 will tell you how many gallons of gas it would take to get to Virginia Tech in your car(20 gallons). You would then multiply that by the price of gas($4), which would = $80.

300/25 will tell you how many gallons of gas it would take to get to Virginia Tech in your friends car(12 gallons). You would then multiply that by the price of gas($4), which would = $48.

So to come up with the difference you would do $80-$48, which is $32.
