Answer: A. = 20fps B. = 5 seconds

Explanation: 10 seconds is the time or t, and the equation given to you is 2t; so, you would multiply 2 by 10 to get your speed of 20 feet per second or 20 fps for short. For part B, all you would have to do divide the number of seconds you get in part A, 10 seconds, by half which is 5. Giving you the answer of 5 seconds.
