Give the step-by-step reasoning process and then the final answer. Two days ago, the temperature in the morning went up 1.5 degrees every 2 hours. If the temperature was 50 degrees at 3 A.M., what was the temperature at 11 A.M.?
At 5 A.M., the temperature was 50 degrees + 1.5 degrees = 51.5 degrees. At 7 A.M., the temperature was 51.5 degrees + 1.5 degrees = 53 degrees. At 9 A.M., the temperature was 53 degrees + 1.5 degrees = 54.5 degrees. At 11 A.M., the temperature was 54.5 degrees + 1.5 degrees = 56 degrees.
The final answer: 56.
