Answer:
7:15 AM
Step-by-step explanation:
First, take 11 - 4 to give you 7. The 11 comes from the starting time, and the four comes from the four and a half hours.
Next, you'll take 45 - 30 to give you 15. Again, the 45 coming from 11:45 and the 30, or 1/2, coming from the four and a half hours before hand.
In the end, you'll get 7:15. Since the starting time was in the AM, and we are going back in time 4 1/2 hours, it will still be AM. So we add AM onto the end of the 7:15 to get your answer.
Hope this helps :)
