mama25angels Posted October 13, 2010 Share Posted October 13, 2010 The amount of water in a tank doubles every minute. The tank is full after 1 hour. When was it 1/4 full? Thanks for any help Quote Link to comment Share on other sites More sharing options...
swainsonshawk Posted October 13, 2010 Share Posted October 13, 2010 I agree: 58 minutes The tank was half full at 59 minutes, then doubled at 60 minutes to be full/ At 58 minutes it was half of half or 1/4 full Fun! I like math questions! Quote Link to comment Share on other sites More sharing options...
