use the drop - down menus to complete each sentence.
in section a, speed is increasing
in section b, speed is increasing
in section c, speed is increasing
in section d, speed is increasing
speed (mph)
time (minutes)

Explanation:

Step1: Analyze section A

In a speed - time graph, if the graph is a straight line with a negative slope, the speed is decreasing.

Step2: Analyze section B

If the graph is a horizontal line (slope = 0), the speed is constant.

Step3: Analyze section C

If the graph is a straight line with a positive slope, the speed is increasing.

Step4: Analyze section D

If the graph is a horizontal line (slope = 0), the speed is constant.

Answer:

In section A, speed is \(\text{decreasing}\). In section B, speed is \(\text{constant}\). In section C, speed is \(\text{increasing}\). In section D, speed is \(\text{constant}\).
