Invert both hour glasses at the same time. Start when the two-minute hour glass finishes. Stop when the five-minute hours glass finishes.
At 0 minutes, turn both the hourglasses.After 4 minutes:The 4 minute hourglass: 0 minutes left.The 7 minute hourglass: 3 minutes left.Turn the 4 minute hourglass.After 7 minutes:The 4 minute hourglass: 1 minute left.The 7 minute hourglass: 0 minutes left.Turn the 7 minute hourglass.After 8 minutes:The 4 minute hourglass: 0 minutes left.The 7 minute hourglass: 1 minute left.Turn the 7 minute hourglass.After 9 minutes:The 4 minute hourglass: 0 minute left.The 7 minute hourglass: 0 minutes left.Now you know you are finished.

None. First, a megawatt is a megawatt - whether it is nuclear or not. Second, a megawatt is a measure of power while a minute is either a measure of time or of angular displacement. In either case, a watt and a minute measure two different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
There are two, 30 second periods in one minute.
There can be no equivalence. An inch is a measure of length in 1-dimensional space while a minute is a measure of time. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

There is no equivalence. A megabyte is a measure of data while a minute is a measure of time. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

Start both timers, when the four minute timer is done, there will be 3 minutes of sand left in the top of the seven minute timer.Restart the four minute timer, while letting the remaining (3 minutes) of sand to drop from the 7 minute timer. (this is your 1st 3 minutes of your nine minute measurement)When the 7 minute timer is done the 4 minute timer will now have 3 minutes of sand in the bottom. Flip the 4 minute timer (when this runs it will be your second 3 minutes of time). At the same time flip the 7 minute timer.When the 3 minutes of sand run on the 4 minute timer, restart the 7 minute timer by this time 3 minutes worth of sand will have gone to the bottom of the timer, resetting it will give you the last 3 minutes of sand for you last 3 minutes of time measuring the 9 nine minutes.
Two hours and one minute.
There is no equivalence. A minute is a measure of time while miles per hour is measure of speed. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
As Fwmh said ," Miles is a unit of length , minutes is a measure of time, the two can not be directly equated" .But if you are looking for How many miles one can run in 180 min? then you can calculate it by simple equation of Distance =Speed X Time where speed is in Miles per Minute and Time is in Minutes.

You have two hour glass: 11 minutes and 7 minutes.Problem, time an egg cooking for fifteen minutes.Step 1. Put water on to boil, as you want the water boiling when you cook an egg.Step 2. Start both the 11 and the 7 minute timersStep 3. When the seven minute timer runs out, you still have four minutes left on the eleven minute timer (11-7=4). Put the Egg in the water now and wait four minutes.Step 4. When the eleven minute timer runs out (the egg has been in the water for four minutes), turn it over and wait till it runs out again.Step 5. When the eleven minute timer runs out the second time the egg is done.4 minutes + 11 minutes = 15 minutes.Step 6. Run the egg under cold water for a minute to cool the shellStep 7. Peel egg and cut into quarters, lightly salt to taste.Step 8. Enjoy eating your hard boiled egg.
