For this case we have that from 2:16 am until 2:16 pm exactly 12 hours have passed. On the other hand, from 2:16 p.m. until 8:16 p.m., exactly 6 hours have elapsed.
If we add, we have that from 2:16 am to 8:16 pm have elapsed: 12 + 6 = 18 hours.
As we ask for the time elapsed between 2:16 am until 8:10 pm we must subtract 6 minutes. So, we have:
18 hours with 54 minutes
Answer:
18 hours with 54 minutes
