First, on Monday I am giving a public talk at the University of Hertfordshire about the paranormal on film….and it is free! Hope you can make it – details here. OK, to the puzzle…..
I have decided to hold a Mouse Clicking Competition. So far, there are only three entrants – John, James and Jack. John can click a mouse 10 times in 10 seconds. James can click a mouse 20 times in 20 seconds. Jack can click a mouse 5 times in 5 seconds. In my competition, the timing period begins with the first mouse click and ends with the final click. Which one of these entrants would be the first to complete 40 clicks?
As ever, please do NOT post your answers, but do say if you think you have solved the puzzle and how long it took. Solution on Monday.
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for theKindle (UK here and USA here) and on the iBookstore (UK here in the USAhere). You can try 101 of the puzzles for free here.
