Answer:
[tex]23.7\frac{miles}{\text{gallon}}[/tex]Explanation: Their Car drove a certain distance on the gas that it had, which is as follows:
[tex]\begin{gathered} \text{ Distance }\rightarrow790miles \\ \text{Gas }\rightarrow33\frac{1}{3}gallons=\frac{100}{3}gallons\rightarrow\approx33.34gallons \end{gathered}[/tex]We need to find the miles per gallon that car had:
Miles per Gallon:
We can find the miles per gallon by simply dividing the total distance by the total amount of gas, which is done as follows:
[tex]\frac{M}{G}=\frac{790miles}{\frac{100}{3}\text{gallons}}=\frac{790\times3}{100}\frac{miles}{\text{gallon}}=23.7\frac{miles}{\text{gallon}}[/tex]Therefore their car got 23.7 miles/gallon on this trip!
