NEED HELP

A normal work day for Carl is from 8:00 a.m. to 4:30 p.m. Carl wants to figure out the degree measure that the hour hand makes while he is at work. Carl believes that if he divides 360 by 12 and multiplies the result by 8.5 he will have the correct degrees the hour hand moves. Is Carl correct? If not, choose the appropriate explanation.

A. Yes, Carl is correct. The process he takes will give him the correct degrees the hour hand moves.

B. No, Carl is incorrect. He must take the number he ends up with and subtract it from 360.

C. No, Carl is incorrect. The hour hand will go around the clock 360 degrees.

D. No, Carl is incorrect. He must first multiply 360 by 12 and then divide by 8.5.

Answer: After trying to work out some of the solutions, I have determined that the correct answer is A.

Step-by-step explanation: 8 - 4:30 = 8.5 hrs.

Because the clock does not rotate 360 degrees, which would be at least 8 - 8, we know that it is less. The only solution that makes sense is the way Carl does it, where the answer is 255 degrees.
