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.
