1) Gathering the data
6 people stuff 500 envelopes in 5 minutes
2) If they work at a steady rate, there must be an inverse relationship between those people.
So, we can set an inverse relationship 1/n, since n is the number times a person can stuff envelope
Therefore we can fill our table:
1 person takes 30 minutes
2 people take 15 minutes
6 people take 5 minutes
3 people take 10 minutes
4 people take 7.5 minutes
5 people take 6 minutes
