Answer:
B. 2 seconds, 5 seconds
Step-by-step explanation:
Looking at the graph, you can see that the vertex, or the point where the graph is at it's highest point, is at 2 seconds and a little over 2 meters in height. So, the time the ball reached it's maximum height was 2 seconds. Looking at the x-axis, which shows the overall time of the ball in the air, you see the ball does not reaching the ground (0 meters) until 5 seconds, so the total time in the air is 5 seconds.
The answer is 11. 5(2) + 1= 10 + 1 = 11.
