2 91.53 
3 88.48 
4 85.17 
5 81.58 
6 77.72 
7 73.58 
8 69.17 
9 64.49

Explanation & Answer

Thank you for the opportunity to help you with your question!

instantaneous velocity (in cm/s) of the object when it is at position 3 = displacement/time=| 91.53-88.48 |/1/60 =3.05/.016667 cm/sec = 183 cm/sec.

Please let me know if you need any clarification. I'm always happy to answer your questions.
