The game lasted for 3 hours and 15 minutes. To find this, you can subtract the start time from the end time: 11:54 PM - 8:39 PM = 3:15. Alternatively, you could convert the times to minutes and then subtract the start time from the end time to get the same result: (11 * 60 + 54) - (8 * 60 + 39) = 3 * 60 + 15 = 195 minutes.
