Julie travelled with 30.5 miler per gallon.
SOLUTION:
Given, On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas.
On the return trip she traveled 235 miles on 8 gallons of gas.
We have to find how many miles per gallon did Julie get on the way there?
We know that,
[tex]\text { number of miles per gallon }=\frac{\text { total distance travelled }}{\text { total number of gallons }}[/tex]
Substituting the values we get,
[tex]=\frac{192+235}{8+6}=\frac{427}{14}=30.5 \text { miles per gallon }[/tex]
Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.
