Question

Brian is driving on a highway. He uses 1 gallon of gas every 50 miles he drives. The distance,D (in miles), he travels on g gallons of gas is given by the following function.D(g)=50gHow far does Brian Drive if he uses 3 gallons of gas?

Answer 1



we have the linear equation

D(g)=50g

so

For g=3 gallons

substitute in the given equation

D(3)=50*(3)

D(3)=150 miles

therefore

the answer is 150 miles
