Final answer:
To check 80 parts, it takes 15 minutes since the inspector checks 16 parts in 3 minutes. The calculation shows it takes 0.1875 minutes per part, leading to 15 minutes for 80 parts. The correct answer is option a.
Explanation:
Calculating Time to Check Parts
As a quality-control inspector, if you can check 16 parts in 3 minutes, we first need to find the time required to check 1 part. To do this, we can use the following calculation:
Time per part = Total time / Number of parts = 3 minutes / 16 parts = 0.1875 minutes per part.
Next, to find out how long it will take to check 80 parts, we use the time per part:
Total time for 80 parts = Time per part × Number of parts = 0.1875 minutes/part × 80 parts = 15 minutes.
Thus, it will take you 15 minutes to check all 80 parts. Therefore, the best answer is:
- a. 15 minutes
