Read the following SAT test question and then click on a button to select your answer.
(A) -10≤v≤-5
(B) -5≤v ≤0
(C) 0≤ v≤5
(D) 5≤v ≤10
(E) 10≤v ≤15
謎底:D
【剖析】
The second coordinate of a point on the graph corresponds to v. From the graph, you can see that for 0≤t≤5, the smallest value of v is 5 and the greatest value is 10 , so 5≤v≤10 .
