Question

Jenna's family is going on a trip to visit relatives. After driving 72 miles, they used 3.2 gallons of gas. Her family has 850 miles remaining on their road trip. The gas tank in their car can hold 15 gallons. They filled the gas tank at the start of the road trip. They plan to only stop when to fill up when their gas tank nears empty. There are plenty of gas stations along their route. How many additional stops will Jenna's family need to make to get to their destination?

Answer 1

72/3.2 equals 22.5, so it’s safe to assume that’s how much has they’d use per mile. they will therefore need about 38 gallons for the next 850 miles. they would need to make 3 more gas stops:)

Answer 2

3 more additional stops

Explanation:

First we need to find how many miles per gallon they are using.

72÷3.2=22.5

1 gallon = 22.5 miles

Then we need to find how much gas we have left. Since we know they started with 15. (The capacity)

15-3.2=11.8

11.8 gallons left

Now we need to find out how many gallons they will need for the rest of the trip.

850÷22.5 (because that is the amount per gallon)

=37.77 ≈37.8

Now we take away the amount of gas we have left.

37.8-11.8=26 (So now they took one stop, 26 gallons left)

26÷15 (because that is the capacity)

= 1.7 ≈ 2

So plus that earlier stop, plus those 2 = 3

Hopefully I was clear as possible, have a good day!
