You have not specified that the two given times are on the same day. Therefore the answer must allow for the fact that the question may concern the period from 11:30 am on one day to 2:30 pm on another day. This is achieved by adding a variable multiple of the number of hours in a day to the answer.
Thus, the answer is (3+24k) hours.
There are seven hours between 730 am and 230 pm. 0.5 + 4 + 2.5 = 7 [1/2 hour to 8 then 4 hours to 12 and 2.5 hours to 2:30] or 14:30 - 7:30 = 7 [14:30 on 24 hour clock is 2:30pm]
6½ hr. OR 6 hr & 30 min It's ½ hr to Noon and 6 hr more until 6:00 pm ===> IF both of those times are on the same day.
