Pixie and Bets were checking out the new Dunkin Donuts across the street when Bets took out two hourglasses from his bag .The smaller one of those could measure 5 minutes and the larger one 7 minutes. Bets asked Pixie if she could measure 16 minutes with the two hourglasses running together? Remember, that if one of the hourglasses finished leaking, then it had to be flipped immediately to keep it running.
