Firstly, you kinda want to "convert" the 2:16 am into pm as well, so to make it 2:16 pm, you will have to add 12 hours, so just remember that. So now you want to find the time difference between 2:16 pm and 8:10 pm. The nest best thing to do would be to find the number of minutes to 3 pm first, and from three pm you know that 8:10 pm is 5:10 more, so now you can add 5:10 plus your 12 hours from before plus the number of minutes it takes to get from 2:16 pm to 3 pm to get your final answer
