Question

Melanie stopped to get gas for her car before beginning a trip. Her odometer

read 42,587 miles, and she filled up her tank with 22 gallons. At the end of her
trip, her odometer read 42,895 miles. What is her car's miles per gallon?

Answer 1

The answer is 14

Explanation:

Answer 2

The rate of car is 1949.7727 miles per gallons .

Explanation:

Given as :

The reading of odometer before filling gas = r = 42,587 miles

The reading of odometer after filling gas = R = 42,895 miles

The quantity of gas filed up inside tank = q = 22 gallons

Let The rate of car's miles per gallon = r

Now, According to question

The rate of car's miles per gallon =
`(\textrm reading of odometer after filling gas)/(\textrm quantity of gas filled)`

i.e r =
`(R)/(q)`

Or, r =
`(42,895)/(22)`

Or, r = 1949.7727 miles per gallons

So, The rate of car = r = 1949.7727 miles per gallons

Hence, The rate of car is 1949.7727 miles per gallons . Answer
