You have the choice between two race cars for a 100 mile race. Both of the cars have a gas tank that can go 21 miles. The first car takes 30 seconds to refuel and goes 185 miles per hour. The second car takes 90 seconds to refuel but goes 200 miles per hour. Which car should you choose to do the 100 mile race faster?

 

Each car starts with a full tank of fuel.
Do not include acceleration speeds.
When the car isn't refueling, it goes its set speed.

You will have to re-fuel each car  FOUR times

Car A    100 miles / 185 m/hr   = 1945.94 seconds   + 4 x 30 = 2065.95 seconds to finish

Car B     100 miles/ 200 m/hr  =   1800  seconds      + 4 x 90 = 2160 seconds to finish   

      Which car would you like?
