I am not great at math, but i am practicing slowly...

Joanne’s odometer read 25,230 miles at the beginning of a trip and 27,215 miles at the end. If she used 35 gal of gas for the trip, what was her mileage (? mi/gal)
now do I subtract 25, 230 from 27,215 and then divide 35?

yes

I got 56.7 m/g

Wow, must have been a SMART car.

Thank you

To find Joanne's mileage (miles per gallon), you need to divide the total number of miles traveled by the amount of gas used. Here's how you can approach the problem:

1. Calculate the total number of miles traveled: Subtract the starting mileage from the ending mileage.
Total miles = Ending Mileage - Starting Mileage
Total miles = 27,215 - 25,230

2. Calculate Joanne's mileage by dividing the total miles by the number of gallons used:
Mileage = Total miles / Gallons used
Mileage = (27,215 - 25,230) / 35

To find the actual value for Joanne's mileage, you need to perform the calculations:

Total miles = 27,215 - 25,230 = 1,985
Mileage = 1,985 / 35

Using a calculator, perform the division:

Mileage ≈ 56.71 miles per gallon (rounded to two decimal places)

Therefore, Joanne's mileage for this trip is approximately 56.71 miles per gallon.
