Answer:
Each inspectors NEEDS to work 20 hours in order to review 320 cars.
Step-by-step explanation:
The amount of time taken to inspect 1 car = 1/2 hr = 0.5 hr
The total people in crew are supposed to be 10
But 2 people are MISSING.
So, the total number of present people in crew = 10 - 2= 8
The total number of cars to be inspected = 320 cars.
Since each car takes 0.5 hour to be reviewed.
So, the time required to review 320 cars = 320 x 05 = 160 hours.
So, the total hours needed to inspect all 320 cars = 160 hours
Now,as there are total 8 crew members.
[tex]\implies \textrm{The number of hours each inspector needs to work} = \frac{\textrm{Total working hours needed}}{\textrm{Toal number of inspectors}} \\= \frac{160}{8} = 20[/tex]
Hence , each inspectors NEEDS to work 20 hours in order to review 320 cars.
