Todd had 6 gallons of gasoline in his motorbike. after driving 150 miles, he had 3 gallons left. compute the slope, or rate of change in the amount of gasoline.

Solution :

Give that,

Todd had 6 gallons of gasoline in his motorbike.After driving 150 miles, he had 3 gallons left.

When Todd had 6 gallons of gasoline in his motorbike he drived 0 miles,

And When he had 3 gallons left , he had drived 150 miles.

Slope or rate of change =

Slope or rate of change of gasoline is negative which means gasoline is decreasing with increase in miles.

Slope or rate of change of gasoline= - 0.02 gallons/mile
