On the first section of the path, the body covered 9m in 3 seconds; in the second section, 15m was covered in 5 seconds, which is equal to the average speed of the body along the entire path.
These tasks: the first section of the path of the body under consideration (S1 = 9 m; t1 = 3 s); second section (t2 = 5 s; S2 = 15 m).
The average speed of movement of the body under consideration along the entire path can be calculated by the formula: Vav. = (S1 + S2) / (t1 + t2).
Calculation: Vav. = (9 + 15) / (3 + 5) = 24/8 = 3 m / s.
Answer: Throughout the entire path, the body in question was moving at an average speed of 3 m / s.
