Post math riddles! Here's one:
>You have two pieces of string that each take one hour to burn. They can burn from either end and you don't know what their lengths are or even if they are of equal length. They also burn at variable rates, that is, they burn fast for some periods and slower for others. Using just a lit match and these two strings, how could measure out 15 minutes of time?

check your phone
fire it up from the middle and the sides

For the sake of the riddle, you are a castaway on some island filled with faggots, and these faggots show up every 16 minutes to do nasty things to your butthole, so you should hide preferably one minute before they show up.

But I'm an engineer

No.

They are still interested in your butthole.
Use one string to keep the flame for convenience sake.
Cut the other string in half, light all four ends. Any time one of the halves burns up completely, take the remaining half and cut it in half, and light the new sides. At any point there are four sides burning and thus the burning will complete in 15 minutes. There are practical limitations to this method, but it should be a suitable approximation.

And I'm interested in their dicks. I just measure out 15 minutes by when my butthole start itching for cock again

OP here. There's a better solution.
light first string from both ends
light second string from one end
wait until first string is burnt
now fire up the remaining string from the other end. the string will burn for exactly 15 mins until it's completely burnt
