Benson Racing is training a new pit crew for its racing team. For its first practice$$ run, the pit crew is able to complete all the tasks in exactly $60$ seconds$$not exactly$$ world$-$class. The second time$$ around, the crew shaves $18$ seconds off its time.

Part $3$

b$.$ Mark$$ Benson, owner of Benson$$ Racing, says that the pit crew must be able to complete all the tasks in less than $17\mathrm{.}7$ seconds in order to be competitive. Based on the answer to part$$ a$,$ how many times will the pit crew need to practice before it breaks the $17\mathrm{.}7-$second $$barrier$?$

Part $4$

c$.$ Is it realistic to expect the pit crew to experience learning improvements$$ indefinitely?

A$.$

$$No$,$ it is not realistic to expect indefinite learning improvements because there are other limitations on the time it takes to complete the task besides the knowledge of the pit crew.

B$.$

$$Yes$,$ it is realistic to expect indefinite learning improvements because there are no other limitations on the time it takes to complete the task besides the knowledge of the pit crew.

C$.$

$$Yes$,$ it is realistic to expect indefinite learning improvements because learning curve theory suggests it$.$

D$.$

It is impossible to give a definite answer.
