Calculations That Determine the Rate of Speed Formulas When time t is constant speed is directly proportional to distance. Average Speed s total distance total elapsed time A v e r a g e S p e e d s t o t a l d i s t a n c e t o t a l e l a p s e d t i m e Average speed contrasts with instantaneous speed. It is usually denoted by d in math problems.
So 1 ms is equal to 36 kmh.
KE ½ m v 2. Kilometers per hour kmh or km h -1 A km is 1000 m and there are 3600 seconds in an hour so we can convert like this see Unit Conversion Method to learn more. This is the formula to be remembered all the time. Velocity equals distance traveled divided by time of travel the speed plus the direction of travel.
