Question

The amount of water flowing into a tank doubles every minute. The tank is full in an hour. When was the tank half full?

Answer 1

 If it doubles every minute, it doubled from half to full the last minute.

Therefore the talk would be full just after 59 minutes.

I hope my answer has come to your help. God bless and have a nice day ahead!
