Jesse notices that his gas mileage jumps from 20 to 40 per gallon when he uses his cruise control. One likely explanation for this is:

a. jesse's car is powered by a biofuel that is not needed while cruising

b. jesse's car is compressing and expanding efficiently

c. jesse's car has an efficient air-to-fuel ratio

d. jesse's car is a hybrid that shuts off extra pistons when it is not accelerating

Answer;

D. jesse's car is a hybrid that shuts off extra pistons when it is not accelerating

Explanation; When cruising, hybrid cars are able to employ electrical energy to drive the car. Moreover, even if a vehicle is not a hybrid, a greater amount of fuel is consumed when one accelerates because the vehicle has to generate a force larger than the force of air resistance in order for it to accelerate. This increased demand of force reduces the vehicle's fuel economy.
