A vehicle is running at a constant speed on a highway. Ignore the initial acceleration at the start and final deceleration when the vehicle runs out of gasoline and comes to halt. Its gas consumption per mile is also constant. The amount of gasoline, in gallons, in the vehicle can be modeled as a linear function G(t)=10-2t, where t is time, in hours. Select all the true statements.
A. Initially, the gas tank has 10 gallons of gasoline.
B. It takes 10 hours for the vehicle to run out of gas.
C. The rate of gas consumption of the vehicle is 2 gallons per hour.
D. The slope of G(t) represents the rate of fuel consumption of the vehicle.
