What is the best methodology in preparing to solve an Elementary Statistics 1 word problem? Is there a sequence of steps in solving the problem? Here is my question in another way.

The New York City Marathon is a highly selective race. One way to gain entry into the race is to qualify based on a time from a prior-completed marathon. The NYC Marathon's organizers use this method to limit admission to the top 12% of marathon runners. If the mean completion time of all marathons is 193 minutes with a standard deviation of 11 minutes, what qualifying time should the NYC Marathon organizers set so that only the top 12% of runners will be admitted entry to the NYC Marathon? Round the solution to one decimal place, if necessary. The qualifying time should be set to _____ minutes to ensure that only the top 12% of runners will be admitted entry to the NYC Marathon. Thank you.
