speed problems\nwhich graph shows a person walking away at a constant rate?\ndistance\ntime\ndistance\ntime\n…

Explanation:

Step1: Recall speed - distance - time relationship

Speed (v=\frac{d}{t}), when speed is constant, (d = vt). This is a linear relationship.

Step2: Analyze each graph

• The first graph is a curve, indicating non - constant speed.
• The second graph shows distance not changing with time (horizontal line), meaning the person is stationary.
• The third graph is a straight line with a positive slope. As time (t) increases, distance (d) increases linearly, which represents a constant positive speed (walking away).
• The fourth graph shows distance decreasing with time, meaning the person is walking towards the starting point.

Answer:

The third graph (the one with a straight positive - sloped line) shows a person walking away at a constant rate.
