WebUsing the average speed formula, calculate the average speed. The distance traveled the first 3 h can be calculated: d 1 = v t = 30 kmph × 3 h = 90 mi. The distance traveled for the second 4 h hours: d 2 = v t = 20 kmph × 4 h = 80 mi. The total distance traveled: d total = d 1 + d 2 = 80 mi + 90 mi = 170 mi. Using the average speed formula ... WebSpeed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, …
