Final answer:
The cycle time per car over the past 2 days is approximately 0.133 (or 8 minutes) per car.
Step-by-step explanation:
The cycle time per car is determined by dividing the total time by the total number of cars produced. In this case, the total time over the past 2 days is 20 hours (10 hours yesterday + 10 hours today) and the total number of cars produced is 150 (100 cars yesterday + 50 cars today). Dividing 20 hours by 150 cars, we get a cycle time of approximately 0.133 (or 8 minutes) per car.
Therefore, the correct answer is not provided in the provided group of answer choices.
