Answer 1

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,

$\text { number of miles per gallon }=\frac{\text { total distance travelled }}{\text { total number of gallons }}$

Substituting the values we get,

$=\frac{192+235}{8+6}=\frac{427}{14}=30.5 \text { miles per gallon }$

Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.
