Average Speed Definition Math. A scalar instantaneous speed cannot be equal to a vector instantaneous velocity. Average speed total distance total time The most common units of measurement for average speed are kph or kilometers per hour mph or miles per hour ms or meters per second and fts or feet per second.
Divide by how many numbers ie. The quantities speed distance and time are all related. So seconds cancel out and were left with kilometers per hour.
But now we have to multiply this number times 3600.
You can multiply time by speed to find any distance. Speed is a rate that is calculated by dividing distance by time. D rt r dt t dr. Furthermore this time is elapsed so as to cover that particular distance.
