The amount of water in a tank doubles every minute. If the tank was full at the 1 hour mark, when was the tank half full?
=============================
It's not homework, I'm just trying to get the actual (reasoned) answer..
=============================
Here is the answer I argued (though, I'm not sure):
2^x = [(2^59)/2]
2^x = 2^58
x = 58
=============================
But, almost everyone argues:
If it doubles every minute, isn't it half full the minute before it's full? ie. 59
=============================
Pretty sure I'm incorrect, I just want to know for sure..
