Question

Distance Traveled and Gas Left in Tank Distance Traveled (in miles) 0 90 180 270 Amount of Gas Left in Tank (in gallons) 15 12 9 6 How many gallons of gasoline does the car have left after it has traveled 330 miles?

Answer 1

4 gallons of gasoline the car has left after it has traveled 330 miles.

Explanation:

We are given with the following data of Distance Traveled and Gas Left in Tank below;

Distance Traveled (in miles) Amount of Gas Left in Tank (in gallons)

0 15

90 12

180 9

270 6

330 ?

As we can see from the table that for every 90 miles of distance traveled, there has been a reduction of 3 gallons of gas which is left in the tank, i.e;

From 90 to 180 - Gas reduced from 12 to 9

This means that in 1 gallon of gas, the distance traveled is =
`(90)/(3)` = 30 miles

So, from distance 270 to 300, the amount of Gas Left in Tank = 6 - 1 = 5 gallons

From distance 300 to 330 miles, the amount of Gas Left in Tank = 5 - 1 = 4 gallons

Hence, 4 gallons of gasoline is left after the car has traveled 330 miles.
