what is the constant of proportionality/unit rate from the following graph?\nspeed\ntotal distance…

Explanation:

Step1: Pick a point from the graph

Choose the point (1, 24): 1 hour, 24 km.

Step2: Calculate unit rate

Unit rate = $\frac{\text{Total Distance}}{\text{Hours}}$ $\frac{24}{1} = 24$

Step3: Identify units

The unit rate is distance per hour, so units are kilometers per hour.

Answer:

24 kilometers per hour
