enson 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 secondsnot exactly world-class. The second time around, the crew shaves 12 seconds off its time. LOADING... Click the icon to view the learning curves table. Part 2 a.

Mark Benson, owner of Benson Racing, says that the pit crew must be able to complete all the tasks in less than 23.76 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 23.76-second barrier? Pit crew need to practice enter your response here times. (Enter your response as a whole number.) Part 4 c. Is it realistic to expect the pit crew to experience learning improvements indefinitely? A. 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. B. 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. 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.
