Answers have more impact when displayed visually. Write an application that
displays the distances one can travel on a full tank of gasoline at di®erent
velocities. Use this formula to calculate distance travelled for a positive velocity,
v:
distance = (40 + 0:05v ¡ (0:06v)
2
) ¤ capacity
where capacity is the size of the automobile's fuel tank. (Note: This simplistic
formula assumes that the car has a one-gear transmission.)
The input to the application is the fuel tank's size; the output are the distances
travelled (and the time taken to do so) for velocities 20, 40, 60, 80, and 100 miles
per hour. Display the answers graphically, so that the answers are pictures like
this:
For a 10-gallon fuel tank:
/A CAR\
40 m.p.h.: =================== -o--o-- 362.4 miles in 9.06 hours
/A CAR\
60 m.p.h.: =============== -o--o-- 300.4 miles in 5.007 hours
