S 270 kmh. Speed or rate r is a scalar quantity that measures the distance traveled d over the change in time Dt represented by the equation r dDt. In science and physics the standard unit of measure for speed is generally meters per second or ms.
Speed is ignorant of direction.
S 750 ms. In the equation Sv t v is the average speed of a body during time t. Calculate speed distance or time using the formula d st distance equals speed times time. V o r.
