### Average time to solve a problem

Posted:

**Wed May 23, 2012 9:53 am**I was wondering if the system could record the average time that a player takes to solve each problem. The system shows the average time that other players take to solve a problem. I guess that players would like to know how faster they are relative to other players. Knowing one's speed is of interest in itself too, because after all there are time constraints in real games.

The system only needs to keep one variable for each problem, if we only want to record the average time. After each (any/correct) trial, the system calculates the new average and updates it.
