21.28s
Explanation:
This is a rate problem.
Number of parts produced = 225
Time taken to produce= 8hours
Rate of production is the amount of parts produced in a duration of time.
Now convert 8 hours to minute;
60 minutes = 1hr
8 hours = 60 x 8 = 480minutes
Now:
Rate of production = = 0.47parts/minute
Now, to produce 10 parts;
It takes;
0.47 parts to be produced in 1 minute
10 parts would be produced in = 21.28s
