Question 1080966: Before I can open my gym locker, I must remember the combination. Two of the
numbers of this three-term sequence are 17 and 24, but I have forgotten the third, and do
not know which is which. There are 40 possibilities for the third number. At ten seconds
per try, at most how long will it take me to test every possibility? The answer is not 40
minutes!

Since there are 40 possibilities for the 3rd number, and given 10 seconds per try, you have 40 x 10, or 400 seconds to try them all; given that you already know the 1st and 2nd numbers. 400 seconds=6 mins.,40 secs.. ☺☺☺☺
