Maria needed 5 gallons of gas to fill her​ car's gas tank. The mileage odometer read 34,300 miles. When the odometer read 34,528 Maria filled the tank with 12 gallons. At the end of the​ trip, she filled the tank with 17 gallons, and the odometer read 34,868 miles. How many miles per gallon did she get for the entire​ trip?

(34,868-34,300)/(12+17) = ?

Long - 19.5862068966

Short - 19.58 or 19.5

Oooo! Ryan didn't learn how to round up correctly, did he?

To calculate the miles per gallon (MPG) for the entire trip, we need to know the total distance traveled and the total amount of gas consumed.

1. Calculate the total distance traveled:
The difference between the starting and ending odometer readings will give us the total distance traveled.
Total Distance = Ending Odometer Reading - Starting Odometer Reading

Total Distance = 34,868 - 34,300
Total Distance = 568 miles

Therefore, Maria traveled a total of 568 miles.

2. Calculate the total gas consumed:
To find the total gas consumed, we need to calculate the gas used during each part of the trip and add them together.
Gas Used during first fill-up: 12 gallons
Gas Used during second fill-up: 17 gallons

Total Gas Consumed = Gas Used during first fill-up + Gas Used during second fill-up

Total Gas Consumed = 12 + 17
Total Gas Consumed = 29 gallons

Therefore, Maria consumed a total of 29 gallons of gas.

3. Calculate the MPG:
To find the MPG, we divide the total distance traveled by the total gas consumed.
MPG = Total Distance / Total Gas Consumed

MPG = 568 miles / 29 gallons

Therefore, Maria got approximately 19.59 miles per gallon for the entire trip.
