Please solve in mathematica using Quantity, UnitConvert and whatever else is needed. Gasoline engine efficiency The drag force F on a car moving at velocity

Please solve in mathematica using "Quantity", "UnitConvert" and whatever else is needed.
Gasoline engine efficiency
The drag force F on a car moving at velocity v is F=Cd**(12) rho v2A,
where Cd is the drag coefficient, A the frontal area, and rho =1.225kgm3 the density of air.
The work done per unit distance against the drag force is F.
a) A VW Golf GTI has a drag coefficient Cd equal to 0.35, and frontal area A of 1.91m?.
What is the work done per unit distance against drag (in Jm) at 70mph?
b) The heat of combustion of gasoline is 45MJkg, and its density is 0.77kgL.
A VW Golf GTI gets about 40mpg on the highway at 70mph on level roads.
How much chemical energy per distance traveled (in Jm) is consumed by at 70mph?
c) What is the efficiency of the engine (work done per energy consumed)?
