Answer:
Speed = 68.75m/s
Step-by-step explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
Given the following data;
Distance = 550m
Time = 8secs
Substituting into the above equation;
Speed, S = 68.75m/s
