There is a Java position written test question. If we know the average payment transaction to DB is 40/per second, how to figure out the roughly number of simultaneous online user to open payment form page? Are there some factors we have to consider? Thank you.

I assume the average time user stay and fill in the payment form is between 3-5 mins. The assumption is the system could handle about 12,000 (40X5X60) simultaneous online users at the peak time. Does it make sense? Thanks.
 
It is sorta covered in the JavaRanch Style Guide.
