The speed of the runner will be 7.9 m/sec.
What is speed?
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while V for the final speed. its si unit is m/sec.
Given data;
Distance,d = 300 m
Time,t=38 second
Speed,s =?
The speed is found as;
Speed = Distance / time
s = d / t
s = 300 m / 38
s = 7.89 m/sec
s =7.9 m/sec
Hence the speed of the runner will be 7.9 m/sec.
