How Many Postage Machines Does Send It Out Need? - Envelope Processing Efficiency

To find out how many postage machines should be used to process the same number of envelopes in one minute as the 24 stuffing machines, we need to calculate the total envelope processing rate for the stuffing machines and then find the equivalent rate for the postage machines.

The stuffing machines process 150 envelopes per minute each. Since there are 24 stuffing machines, the total envelope processing rate is: 24 stuffing machines * 150 envelopes per minute per machine = 3600 envelopes per minute

To determine the number of postage machines needed, we need to find an equivalent rate in envelopes per minute. Since each postage machine processes envelopes at a rate of 4 envelopes per second, we can convert this to envelopes per minute: 4 envelopes per second * 60 seconds per minute = 240 envelopes per minute

Now, we can calculate how many postage machines are needed: Number of postage machines = Total envelope processing rate / Envelope processing rate per postage machine Number of postage machines = 3600 envelopes per minute / 240 envelopes per minute Number of postage machines = 15 postage machines

Therefore, to process the same number of envelopes in one minute as the 24 stuffing machines, Send It Out should use 15 postage machines.
