Question
You are in charge of a crew that inspects cars. Each car takes approximately 1/2 hour for 1 person to inspect. The normal crew has 10 people, but this crew is missing 2 people. If you have 320 cars that need to be inspected, how many hours will each of the inspectors need to work?20 hours16 hours32 hours40 hours
Solution
To solve this problem, we need to follow these steps:
-
Determine the number of inspectors: The normal crew has 10 people, but this crew is missing 2 people. So, we have 10 - 2 = 8 inspectors.
-
Determine the total time needed to inspect all cars: Each car takes approximately 1/2 hour for 1 person to inspect. So, for 320 cars, it would take 320 * 1/2 = 160 hours in total.
-
Determine the time each inspector needs to work: The total time needed is 160 hours, and we have 8 inspectors. So, each inspector needs to work 160 / 8 = 20 hours.
So, the answer is 20 hours.
