If you enjoy riddles, teasers, or posers then this is just for you. Each comes with a postulated question that tricks and challenges the mind. Some are easy and some are hard. Try not to over think them and enjoy the imagery. The answer to the riddle, poser, or teaser is below. Try not to look until you are truly ready.

Answer

The commuter has walled for 55 minutes before his wife picks him up. Since they arrive home 10minutes earlier than usual, this means that the wife has chopped 10 minutes from her usual trave time to and from the station, or five minutes from her travel time to the station. It follows that she met her husband five minutes before his usual pick-up time of five o’clock, or at 4:55. He started walking at four o’clock, therefore he walked for 55 minutes.

The man’s speed of walking, the wife’s speed of driving and the distance between home and station are not needed for solving the problem. If you fried to solve it by juggling figures for these variables, you probably found the problem exasperating.
