Answer:

C. 8

Step-by-step explanation:

The elevator goes up 51 floors in 12.75 seconds.

Take 51/12.75 to get the number of floors per second.

51/12.75=4

4 floors multiplied by 2 seconds equals 8.

Therefore, answer C is correct.

vitfil [10]

Answer:

None of the answer choices.

Step-by-step explanation:

The pattern to this problem is multiply by 4, and subtract 3. However when doing 17 * 4, you get 68. Look how both of the answer chouces start with 68, and we haven't even subtracted 3 yet. This shows that the answer choices are wrong.
