In a factory, an assembly line can manufacture 39 widgets per second. In another factory, 6 widgets are combined to make 1 whooz
Rudik [331]
Given:
39 widgets per seconds
6 widgets to make 1 whoozit

3,500,000 whoozits * 6 widgets/whoozits = 21,000,000 widgets
21,000,000 widgets / 39 widgets/sec = 538,461.54 seconds

1 day = 24 hours
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 3600 seconds

3,600 seconds * 24 hrs = 86,400 seconds 
538,461.54 seconds / 86,400 seconds per day = 6.23 days.

B. 6 days.
