Answer

Answer:

D. 4.5 and 12 seconds

Explanation:

Step1: Locate 600 on altitude - axis

Find 600 feet on the y - axis (altitude).

Step2: Draw horizontal line

Draw a horizontal line at y = 600 across the graph.

Step3: Find intersection points

Find the points where the horizontal line intersects the rocket's altitude - time graph.

Step4: Read x - values

Read the corresponding x - values (time). The intersections occur at approximately 4.5 seconds and 12 seconds.
