Final answer:
The average speed is calculated by dividing the distance of 547 meters by the time of 77 seconds, resulting in approximately 7.10 m/s, which aligns with option A) 7.09 m/s.
Step-by-step explanation:
The question asks to calculate the average speed given the distance traveled and the time taken. To find the average speed, you need to divide the total distance by the total time. The formula for speed (v) is v = distance (d) / time (t). Substituting the given values, v = 547 m / 77 s, we get the average speed as approximately 7.10 m/s, which is closest to the option A) 7.09 m/s.
