A = 187.5 cm^2
Where's the rest of the question?
Answer: 17 miles per hour.
Step-by-step explanation:
1. To solve this problem you must apply the following formula:
=Δx/Δt
Where Δx is the position variation and Δt is the time variation.
2. Then, based on the graph shown attached, you have:

3. Therefore, you have that the result is:

1. ALL
2. 10,3,-1,-5,-11
3.-1/2, -2/3, 7/12, 0.82
