You’re on a routine patrol, driving along at 40 mph (or 60 fps). (Half of 20 = 10 and 20 + 10 is 30) so if you were going 20 mph, you would be moving at the rate of approximately 30 fps.Ĥ0 MPH, half of 40 is 20, 40 + 20 = 60 they are moving 60 FPSĥ0 MPH, half of 50 is 25, 50 + 25 = 75 they are moving 75 FPSĦ0 MPH, half of 60 is 30, 60 + 30 = 90 they are moving 90 FPS PRACTICAL USE OF FPS – Routine Patrol
If you multiply 20 by 1.5, you take half of 20, which is 10, and add it to 20, which will give you 30. If you want to multiply by 1.5, you do it by adding. Now to change MPH to FPS, multiply by 1.5 instead of 1.47. The first thing you do is round off 1.47 to 1.5. If you don’t mind being off a bit in your calculations or would like to explain this concept to your students but don’t feel like multiplying by 1.47 every time you want to convert mph to fps, there is an easy way of doing all this. There are 5280 Feet in a mile and 3600 Seconds in an hour. To convert miles per hour to feet per second, multiply the miles per hour figure by 1.47. If you are moving at the rate of 40MPH, how many feet do you travel in a second? At 40 miles per hour, you are traveling 58.8 feet per second. It would be a good skill to have to convert MPH to Feet/Sec (FPS). When driving through an exercise, the student does not have a mile or an hour to decide.
But for Emergency Vehicle Operations Course (EVOC), training may not be the best reference for measuring time and distance. It’s a natural unit of reference that everyone is familiar with in driving discussions. We measure time and distance using the car’s speedometer, which indicates speed measured in miles per hour (mph), the time it takes to cover a given distance. When you are driving on patrol, you are managing time and distance. The first part of this article may be simplistic but hang in there for a while.
