The average speed of a moving object is given by the ratio of the total distance travelled and the elapsed time: save=dΔt Average speed is a scalar quantity. Thus, it is only defined by its magnitude, as it is with distance. On the...
The first reported continuous traffic count sustained over a year was carried out by Shelton (1938). In this study, hourly manual traffic counts were recorded for all hours of the day for 366 consecutive days. Manual counting is expensive since it requires considerable human labor. Mechanical ...
Racing cars at the Indianapolis Motor speedway now routinely travel at an average speed of 225 mi/h. What is this speed in kilometers per hour? A car's speed is 237.8% of a bicycle. If the car is going 24.804 mph faster than the bike, what is the car's ...

For the sake of familiarity, I’m going to say we’re driving 60 MPH, just like you would on the interstate. That’s the speed limit in space, so don’t let the galactic fuzz catch you speeding. So we’re planning our trip. We’re talking about going 93 million miles at 60 ...
Human health was another area of major impact. There were 39 known deaths due to vehicle and train accidents. Five died in snowmobile accidents, two froze to death, and another 32 died of heart attacks resulting from overexertion, due mainly to snow shoveling. The storm also induced numerous...
What controls the speed of a hurricane? We just watched Hurricane Joaquin slow down to 3mph and became almost stationary over the southern Bahamian islands, then he made a northern turn and is moving much faster 10mph and probably faster by now. 9 Madeline ⚠ Can you please add hurricanes...
Which should come as no surprise, because the single largest factor in the severity of any crash isspeed, and while a car can easily go 80MPH or more, most riders top out at about 25MPH (and that's going downhill) Please read:http://biodieselhauling.blogspot.com/2012/06/please-ride-...
By mid decade the public’s desire will be the bicycle, electric or the usual human powered one. Only those will be driving cars who had the foresight to prepare for the greater depression. The average person will not be able to afford one. Trin...
An average is the central value for a given set of numbers. It represents the most typical value in the given set. We find the average of a set of numbers by adding them all up, and dividing by the amount of numbers in the set....
