The appropriate interrogative pronoun that should be used to complete the sentence is the word "whom". The sentence would be: Whom did you say about my work? We used whom because it indicates that the action is done to the speaker. In other words, whom is used when the verb is done by the object.

Answer: 67.5 seconds
Explanation:
The marble is traveling at a speed of 1/30 length units per 2.25 seconds.
Use direct proportion to find out the amount of time it would take to cover the whole length:
1/30 : 2.25 seconds
1 : x
1/30 x = 2.25 seconds
x = 2.25 ÷ 1/30
x = 2.25 * 30/1
x = 67.5 seconds
<em>67.5 seconds is 1 mins and 7¹/₂ seconds. </em>
