Final answer:
The average speed of the ghost crab was 1.67 m/s, calculated by dividing the distance traveled (15 meters) by the time taken (9 seconds).
Step-by-step explanation:
Calculating Average Speed
To calculate the average speed of the ghost crab, we can use the formula:
Speed = Total Distance / Total Time
The ghost crab ran 15 meters in 9 seconds. Therefore, the average speed of the ghost crab would be:
Speed = 15 meters / 9 seconds = 1.67 meters per second (m/s)
It's important to note that in calculating speed, we are discussing a scalar quantity, which does not include direction. We also know that this is an average speed, meaning it could have varied at different points during the run, but overall, this rate was maintained.
When comparing this to other scenarios, we can understand better. For instance, a sprinter may have an average running rate of 9.09 m/s, which is significantly higher than the crab's speed. This type of context helps in understanding the nature of the movement.
