Question

Peggy filled her van's gas tank and noted that the odometer read 21,373.8. After the next fill-up, it read 21,771.6. It took 19.5 gal to fill the tank. How many miles per gallon did the van get?

Answer 1

20.4 miles per gallon

Step-by-step explanation:

First, we need to know the number of miles between 21,373.8 and 21,771.6, so the difference is equal to:

21,771.6 - 21,373.8 = 397.8

Now, we know that the van got 397.8 miles with 19.5 gals, so to know the number of miles per gallon, we need to divide 397.8 by 19.5:

`\frac{397.8\text{ miles}}{19.5\text{ gals}}=20.4\text{ miles per gallon}`

Therefore, the van got 20.4 miles per gallon
