2 dni temu · The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).
5 dni temu · Global Positioning System (GPS) uses radio waves and satellite technology to calculate the time difference between Satellites, which it then converts into an approximation of distance. It can also be used to measure speed by determining the amount of distance traveled in a given amount of time.

5 dni temu · The simplest way to convert knots to miles per hour is to multiply the number of knots by 1.151. For example, if you're trying to convert 17 knots to miles per hour, you would multiply 17 by 1.151 and get 19.6. Therefore, 17 knots is equal to 19.6 miles per hour. To learn how to convert knots to feet per mile, read on!

4 dni temu · Hence, x = 3 km = 3 x 1000 m = 3000 m. The time given to us is 20 minutes, and we need to convert it to seconds. Thus, time (t) = 20 minutes = 20 x 60 seconds = 120 seconds. Formula: We will now apply the formula, average speed = distance covered / time taken. Thus: Average speed = Distance covered (x) / Time taken (t) = 3000 m / 120 s = 2.5 m/s.
