Question

Vehicle a averages 14 miles per gallon of gasoline, and vehicle b averages 36 miles per gallon of gasoline. at these rates, how many more gallons of gasoline does vehicle a need than vehicle b to make a 1,008-mile trip?

Answer 1

So first we need to find the amount of gallons that it would take for each vehicle to travel 1,008 miles. We can do this by multiplying and canceling units:

Vehicle A:
`(1,008mi)/(1)* (gal)/(14mi)=72gal`

Vehicle B:
`(1,008mi)/(1)*(gal)/(36mi)=28gal`

So we found that Vehicle A needs 72 gallons to make the trip, and Vehicle B needs 28 gallons to make the trip.

Let's find the difference:

`72-28=44`

Therefore, Vehicle A needs 44 more gallons of gasoline than Vehicle B to make the trip.
