The formula to calculate the speed is therefore: (L x 60) (T x 100) = V, where L is length in feet, T is time in seconds and V is speed in knots. For example, if on a 28ft yacht it took three and a half seconds to pass an object, the calculation would be : (28 x 60) divided by (3.5 x 100) = 4.8 knots.
