| 629401 | 2008-01-11 02:22:00 | How does a GPS tell a car's speed? I have seen some in-car GPS units that can tell a car's speed. How is this? Is the GPS hooked up to the speedometer? And if you buy a portable handheld GPS, can it tell your car's speed? |

| 629403 | 2008-01-11 03:47:00 | No, it measures the distance that you've traveled and then divides it by the time it took you to give you your speed ie: Distance/Time = Speed |

| 629404 | 2008-01-11 04:27:00 | You bet it can tell the speed of the vehicle its just time and distance. One of my customers fired a truck driver because they clocked him at 120 kph southbound down Bombay hills. Think of it as a high tech stopwatch over a known distance. If you are going to commit a crime in you car remember to turn your gps off. C1 |
