text: what is the average speed of this bus??? we have three-hundred, 450 pound men, cruising down the hi-way in a bus going 190 miles per hour,  if one of these men moons an oncoming car and slows the bus down to 150 miles per hour for 1 minute, what would the average speed of the bus be over a 200 mile course??? its definately not a bus, cause 1) no bus take 300 people 2) if the weight of one person is 450. lbs i.e. 450*300 = 1,35000 llbs. = 61,234 kgs = 61 tons no bus can take that weight.
