* A lumen is the same as Lux and is what many modern light meters will calculate their measurement in. The next step is to calculate the number of watts. One lumen is = 0.001496 watts. This is pretty simple, after you have your total number of lumens from step 2.
Quick Answer. The formula for speed is s = d/t, where s equals the speed, d is the distance covered and t is the time it took to cover the distance. The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation. Continue Reading.
In order to find the speed of a horse we must understand the formula for speed. The formula is. v = Îs/Ît. where Îs is the change in distance and Ît is the change in time. This is the only formula that is needed in order to find the speed or velocity of a horse.
