To find out which option would produce a batch of magazines in less time, we need to compare the production rates of the old and new printers.
The old printers produce a batch in 30 minutes, which means they can produce (60/30) = 2 batches per hour.
The new printers produce a batch in 16 minutes, which means they can produce (60/16) = 3.75 batches per hour.
To determine which option would be faster, we compare the number of batches that can be produced:
- 6 old printers can produce 2 * 6 = 12 batches per hour.
- 2 new printers can produce 3.75 * 2 = 7.5 (or 7) batches per hour.
Therefore, 6 old printers would produce a batch of magazines in less time than 2 new printers.
To calculate the time difference, we compare the production rates:
The old printers take 30 minutes to produce a batch.
The new printers take 16 minutes to produce a batch.
The time difference would be 30 - 16 = 14 minutes.
Therefore, using 6 old printers instead of 2 new printers would take 14 minutes less to produce a batch of magazines.
It takes 30mins for 5 old printers to produce a batch of magazines
it takes 16mins for 4 new printers to produce an identical batch of magazines
which of the following would produce a batch of magazines in less time; 6 old printers or 2 new printers
how much less time would this take?
