What is it that speaks without any words? And can be loudly and distinctly heard? Will drive away friend, and foe alike. And is enough to make a stolid man’s face alight?
Mario is testing out a new car at the racetrack. His grandmother took it for a mile lap and averaged 30mph. How fast does Mario have to drive in the second lap to average 60mph for the two miles?
90mph is an alluring answer, but it’s impossible. At 90mph the second lap would take 40 seconds. If Grannie’s first lap at 30mph took 2 minutes, traveling 2 miles in 2 minutes and 40 seconds is an average speed of 45mph. Traveling an average speed of 60mph for 2 miles would take 2 minutes and since the grandma’s lap took all of those 2 minutes, even if Mario could break the sound barrier he wouldn’t be able to average 60mph.
A man was looking through a window on the 6th floor, opened it, thought for a minute then jumped, passing through the open window, but he was not injured. How was this possible?
