Given that in a room there is an amoeba (only one) and it duplicates itself every second and will fill the entire room in 1 hour. When (in seconds) will the amoebas fill up half the room?

When (in seconds) will the amoebas fill up half the room? 

 

Since the amoeba doubles every second, the room was half full one second before the room was full. 

 

So the answer is at mark 59 minutes 59 seconds, or 3,599 seconds
