my car gets 18 miles to the gallon. I need to drive 248 miles. my gas tank holds 35 gallons.how many miles can I go before I have to refill?
35 * 18 = _______ miles
Let 18miles to the gallon be X
18miles=X
M=35g
let cross multiply
18*35=630miles before you refill
To calculate how many miles you can go before you have to refill your gas tank, you can use the following steps:
Step 1: Determine the car's mileage per gallon
Since your car gets 18 miles to the gallon, this means it can travel 18 miles for every 1 gallon of gas it uses.
Step 2: Calculate the total number of gallons needed
To calculate the total number of gallons needed to cover a specific distance, divide the total distance by the mileage per gallon.
248 miles / 18 miles per gallon ≈ 13.78 gallons
Step 3: Determine the remaining fuel capacity in your gas tank
If your gas tank holds 35 gallons, you need to subtract the total number of gallons needed from the gas tank capacity to know how much fuel you'll have left.
35 gallons - 13.78 gallons ≈ 21.22 gallons
Step 4: Calculate the remaining distance
Multiply the remaining fuel capacity by the mileage per gallon to determine the remaining distance you can travel.
21.22 gallons * 18 miles per gallon ≈ 381.96 miles
Therefore, you can go approximately 382 miles before you have to refill your gas tank.
