WebThus we can find the average speed as: Average Speed = (Total distance)/ (Total Time) = (1800 + 1800)/ (30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 … http://greenharbor.com/fffolder/speedtime.pdf
WebMar 26, 2016 · Using the rate, or speed formula, you can easily figure out the ball’s average speed during the 2nd second of its fall. Because it dropped 16 feet after 1 second and a total of 64 feet after 2 seconds, it fell 64 – 16, or 48 feet, from t = 1 second to t = 2 seconds. The following formula gives you the average speed:
WebDetermine the average speed and the average velocity. The physics teacher walked a distance of 12 meters in 24 seconds; thus, her average speed was 0.50 m/s.
