Respuesta :

B. Between 20 and 25 minuets

Brooke's speed is decreasing between 20 and 25 minutes. According to the graph Brooke's speed is decreasing during that time period.

Answer:

B) between 20 and 25 minutes

Step-by-step explanation:

First, note that the line from 0 minutes to 5 minutes increases 40 mph. (+40)

Next, note that the line from 5 minutes to 10 minutes increases 10 mph. (+10)

Next, note that the line continues to stay the same from 10 minutes to 20 minutes. (+0)

Now, we get to the last part, which shows a drop from 50 mph to 40 mph (50 - 40 = 10; -10 mph drop)

-------------------------------------------------------------------------------------------------------

We can note that her speed starts at 40 mph, but drops to 10 mph at 5 - 10 minutes. However, note that there is no answer choice for it, and so the next logical choice is the drop of speed from 20 - 25, which is a 10 mph drop.
