6AM AGAIN. AFTER ALL, WHAT DIFFRENCE DOES THE SPEED OF LIGHT MAKE TO THE ANSWER? IT'S IRRELEVANT- ONLY THE SPEED OF THE ROATION OF THE EARTH MATTERS HERE THE FLY WOULD HAVE TRAVELLED 90 MILES. THE TRAINS ARE 100 MILES APART, AND THE TRAINS ARE TRAVELLING TOWARD EACH OTHER AT 40 AND 60 MPH, THE TRAINS WILL MEET IN ONE HOUR. THE FLY WILL HAVE BEEN FLYING FOR AN HOUR AT 90 MPH AT THAT POINT, SO THE FLY WILL HAVE TRAVELLED 90 MILES NOT 12 SECONDS. THERE ARE 7 SEGMENTS FROM THE FIRST FLAG TOT THE EIGHTH, AND 11 FROM THE FIRST TO THE TWELFTH. HE RUNS EACH SEGMENT IN 8/7 SECONDS; THEREFORE, 11 SEGMENTS TAKE 88/7= 12 4/7 SECONDS YES, THERE IS A POINT ALONG THE PATH THAT THE MONK OCCUPIES AT PRECISELY THE SAME TIME ON BOTH DAYS. IF YOU ASSUME THAT THE THERE ARE TWO MONKS, ONE DOES THE ROUTE FROM THE TOP, AND THE OTHER FROM THE BOTTOM. AT SOME POINT, THEY MUST MEET. THERE'S YOUR POINT
