Question

Haley's car gets at least 17 miles per gallon. If she plans a trip that is 250 miles, what is the minimum number of gallons she'll need?

Answer 1

17 miles >>>> 1 gallon
250 miles >>>> x gallons

x=250*1/17=14.706 gallons

She would need at least 15 gallons

Answer 2

`14.7 gallons`

Explanation:

To find out how many gallons Haley will need to travel 250 miles, we apply a simple three rule.

`17 miles\longrightarrow 1 gallon\\ 250 miles\longrightarrow x\\ x=((250 miles)(1gallon))/(17miles)= 14.7 gallons`
