if we have 300, five-hundred pound men, running at 37 miles per hour, what is their average speed over a 10 mile course if one of these large men stops for 5 minutes to eat a 3 foot frankfurter???

Alright, so the course is ten miles and they are running at 37 miles per hour. So everyone finishes in 10/37 hours, except one man, who finishes in 10/37 + 5/60 hours. Thus, their average time is (299*10/37 + 10/37 + 1/12)/300 = 36037/133200 hours. They ran for 10 miles, so we take 10 over this to get 1332000/36037 mph as their average speed, which is about 36.96201126 mph

don't be silly, 500 pound men can't run at 37 miles per hour.
