Re: Packing rates.
Hi nicboo;
Welcome.
That is how many per minute now you just multiply by 60 to get how many per hour.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Packing rates.
Hi nicboo
If someone packs 468 envelopes in 1hr 53min=113 min, then in 1hr=60 min he will pack 60/113 of 468 which is 28080/113 envelopes per hour. That is close to 248.5 envelopes per hour.
Now, if they pack 845 envelopes in 3.5 hrs then in 1hr they will pack 3.5 envelopes less, that is 845/3.5=8450/35=1690/7 envelopes per hour.
The limit operator is just an excuse for doing something you know you can't.

Re: Packing rates.
hi nicboo
Welcome to the forum.
This is how you can devise your own formula for this:
Think of a very easy example. Say you want to pack 1000 envelopes and you know you can do 200 per hour.
That's two hundred in the first hour, another two hundred in the second hour, ............, another two hundred in the fifth.
Can you see this will take 5 hours?
So what is the connection between the three numbers ?
So now put words in place of the numbers:
This time will be in hours. Times by 60 to change to minutes.
