Here are the durations for each pair of times: 1. Duration from 2:15 p.m. to 2:50 p.m. Step 1: Subtract the start time from the end time. 2 hours 50 minutes - 2 hours 15 minutes = (2-2) hours (50-15) minutes = 0 hours 35 minutes The duration is 35 minutes. 2. Duration from 1:20 p.m. to 2:30 p.m. Step 1: Calculate the time from 1:20 p.m. to 2:00 p.m. 2 hours 00 minutes - 1 hour 20 minutes = (1 hour 60 minutes) - (1 hour 20 minutes) = 40 minutes Step 2: Add the remaining time from 2:00 p.m. to 2:30 p.m. 40 minutes + 30 minutes = 70 minutes Alternatively, this is 1 hour and 10 minutes. The duration is 1 hour 10 minutes. 3. Duration from 2:25 p.m. to 3:10 p.m. Step 1: Calculate the time from 2:25 p.m. to 3:00 p.m. 3 hours 00 minutes - 2 hours 25 minutes = (2 hours 60 minutes) - (2 hours 25 minutes) = 35 minutes Step 2: Add the remaining time from 3:00 p.m. to 3:10 p.m. 35 minutes + 10 minutes = 45 minutes The duration is 45 minutes.
