Speed Calculating speed - Any change over time is called a rate. - If you think of distance as the change in position then speed is the rate of change in position. - Speed Equation speed(inmcters/second)=frac (distance(inmeters)){time( s=(d)/(t) - In Sl units, distance is measured in meters, and time is measured in seconds. square A person walks 5 meters in 3 seconds The speed of the person is m/s.

To calculate the speed of the person, we can use the speed equation: Given that the person walks 5 meters in 3 seconds, we can substitute the values into the equation: m/sTherefore, the speed of the person is 1.67 meters per second.
