Question

Trevor is charting the motion of his pet tortoise across the floor. The diagram below shows its position every 60 seconds.



Which of the following statements about the motion of the tortoise is true?
A.
The tortoise is moving at a constant speed.
B.
The tortoise's speed is decreasing through time.
C.
The tortoise's speed is increasing through time.
D.
The tortoise's position is not changing through time.

Answer 1

To determine the correct statement about the motion of Trevor's tortoise, we need to analyze the diagram showing its position at different intervals.

1. **If the tortoise's position is changing every 60 seconds** (meaning it is moving from one point to another), statements A, B, and C could potentially be analyzed based on whether the distance covered is the same (constant speed), decreasing (speed is decreasing), or increasing (speed is increasing).

2. **If the tortoise's position does not change** between measurements, this would support statement D, indicating it is stationary.

Without seeing the diagram, I can't draw specific conclusions, but here’s how you would approach it:

- If the distances the tortoise covers in each 60-second interval are equal, then **statement A (the tortoise is moving at a constant speed)** is true.

- If the tortoise covers less distance in subsequent intervals, then **statement B (the tortoise's speed is decreasing)** would be true.

- If it covers more distance in each subsequent interval, then **statement C (the tortoise's speed is increasing)** would be true.

If the positions are identical at each time mark, then **statement D (the tortoise's position is not changing through time)** would be true.

Please check your diagram, and based on the changes in position of the tortoise over time, select the appropriate statement.
