  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 .
