Question

All is driving on a highway. He uses one gallon of gas every 30 miles he drives. The distance, D (in miles), he travels on gfollowing function.D(g) = 30gHow far does All drive if he uses 4 gallons of gas?

Answer 1

The function represents the distance when he uses g gallons on a highway.

The given function is:

`D(g)=30g`

If we want to find how far does all drives if he uses 4 gallons of gas, we need to replace g=4.

Then:

`\begin{gathered} D(4)=30(4) \\ D(4)=120 \end{gathered}`

Hence, he will be 120 miles away if he uses 4 gallons of gas.
