"If you add one quarter of the time from noon till now to half the time from now till noon to-morrow, you will get the time exactly." What was the time of day when the professor spoke? 58.--A TIME PUZZLE. How many minutes is it until six o'clock if fifty minutes ago it was four times as many minutes past three o'clock? 59.--A PUZZLING WATCH. A friend pulled out his watch and said, "This watch of mine does not keep perfect time; I must have it seen to. I have noticed that the minute hand and the hour hand are exactly together every sixty-five minutes." Does that watch gain or lose, and how much per hour? 60.--THE WAPSHAW'S WHARF MYSTERY. |
