Question

Piper is driving on a long road trip. She currently has 11 gallons of gas in her car. Each hour that she drives, her car uses up 1.75 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after tt hours?

Answer 1

Answer:

4 gallons

Step-by-step explanation:

In order to solve this you need to multiply 1.75 times 4 for the total amount of gallons used. That would equal 7. Since we need to find how much she has left, we need to subtract. 11-7=4.

4 gallons of gas will be left after 4 hours of driving.

Hope this helped!! :)

Answer 2

Answer:

begins the trip with 14 gallons of gas in her car.

The car uses up one gallon of gas every 30 miles.

Let g represent the number of gallons of gas she has left in her tank, and let d

represent the total distance

Step-by-step explanation:d = 30(14 - g)

:

For example, if she uses two gallons, there will be 12 gal left in the tank; g=12

d = 30(14 - 12)

d = 30(2)

d = 60 mi  Here you go
