This puzzle comes to me via the same source as the previous four. Using only a 4 minute and Avelyn Ts minute hourglass or Egg Timer 5 Minutes timer how would you measure exactly 9 minutes?
Before reading the answer can I interest you in a clue? The puzzle appears quite difficult. Before we can take a run Is Calum Von Moger Natty it we're going to have Timdr build some tools, we will then use them Tlmer combination.
Addition The simplest of our tools. Ebg can combine hourglasses in series. We could use the 4 and the Tabata Joi one after the other to measure 11 minutes. Or any other simple combination. Minures If we were to start both hourglasses together, flip the 4 when it reaches the end the difference between it ending for the second time and the 7 minute ending is 1 minute.
The difference between 4 runs of the 4 and 3 Tiimer of the 7 would be 16 as against 21 Egg Timer 5 Minutes. So 5 Timed.
Early Egg Timer 5 Minutes We could for example start both timers together. When the 4 minute hourglass runs out we know that the 7 minute hourglass has run for 4 minutes Egg Timer 5 Minutes and so must have 4 minutes of sand in the bottom. If we Efg it now it will necessarily run for 4 minutes. Bringing it together We already have a solution. We said if we start them both together and flip the 4 minute hourglass every time it runs out the difference between the 7 minute hourglass ending and the and the 4 minute hourglass ending for the second time is 1 minute.
As shown: Clearly though a better solution would be one that didn't require us to wait 7 minutes before we start. And there is a solution that allows this.
We need to add 2 minutes on to the end of the 7 minute hourglass. Since the twice-flipped 4 minute hourglass will stop at 8 minutes we can flip our 7 minute hour glass here for the second Tomer. At this point it will have been running for 1 minute, we will flip 1 minute's worth of sand back to the top and it will run for another 1 minute.
This will total 9 minutes. As shown: Not sure how to rate this for difficulty. But prior to that it seems very hard. Where next? PayPal I always think it's arrogant to add a donate button, but it has been requested. If I help you get a job though, you Minutss buy me a pint!
