Q. You have two hourglasses - a four-minute glass and a seven minute glass. You want to measure nine minutes. How do you do it
The best thing you could do is askĀ
Mark:
T=0: start 4 and 7
T=4: 4 empty, flip 4
T=7: 7 empty, flip 7
T=8: 4 empty, 7 divided 6/1, flip 7
T=9: 7 empty
Or better still, buy a watch!
