Let's Exercise Our Minds


I have a 3-minute egg timer and a 4-minute egg timer.
The problem is that I need to measure 5 minutes. Can this be done with the two timers?
The timers are the old-fashioned kind that contain sand ... and you turn them over when they have completely emptied the sand into the bottom chamber.
Post your answer in the comments. Good luck!

ha..ha..ha..
try again.
I will give you the answer perhaps after 5 more tries (?)
@ Nelia and Lucille, do not get discouraged. The idea is to exercise our brain lest it gets decrepit!

Hayyyyyy, Inaantok na ako!!!!
I thought this one will elicit some responses, but no luck!
I do not know what you guys would like to imply with your passivity. Not interesting enough?
Anyway, before it gets into the older posts section, I hope someone could harness enough courage to even try, like Nel.
Thanks to all of you!
