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,

`=(192+235)/(8+6)=(427)/(14)=30.5 \text { miles per gallon }`

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