This is difficult to answer coz it depends on the power of your heater and original temperature of the water. Say a 1000W heater, might be tens of seconds, if the water was at room temperature.
100 degrees
Water evaporates at 100 so it would not be possible to boil an egg at 200
100 miles at 100 mph would take 1 hour
It would take: 1 hour at 100 mph or 2 hours at 50 mph
As with any other "how long does it take" question, that would depend on the speed. At the speed of light (which we CAN NOT even approach with current technology) it would take 100 years. At slower speeds, it would obviously take much longer.
100 years
It depends on your speed.
8.30 minutes
You didn't tell us how long it took to walk those 3.33 meters, so it is impossible to know how long 100 meters would take.
If you spent 100 EVERY day... it would take more than 27 YEARS !
It would take: (220/100) times 9.2 = 20.24 seconds
It would take about 3.2 years.
