3 pm is 15 hours, so 15-3 1/2 = 11 1/2 hours or 11:30 hours
2 hours.
1 hour = 60 mins → ½ hour = ½ × 60 min = 30 min 3 hours after 11:20 am is: 11 + 3 = 14, but as this is greater than 12, subtract 12 and swap am/pm → 14 - 12 = 2, am → pm; thus 3 hours after 11:20 am is 2:20 pm. ½ hour after 2:20 pm is 30 mins after 2:20 pm→ 20 + 50 = 50 → ½ hour after 2:20 pm is 2:50 pm Thus 3½ hours after 11:20 am is 2:50 pm.
There are 2+12k hours where k is an integer.

3 pm is 15 hours, so 15-3 1/2 = 11 1/2 hours or 11:30 hours
16 hours(11 pm, 12 midnight, 1 am, 2 am, 3 am, 4 am. 5 am, 6 am, 7 am, 8 am, 9 am, 10 am, 11 am 12 noon, 1 pm, 2 pm, 3 pm.)
11 am to 11 pm is 12 hours and then add 2 more hours to get 14
10 & 1/2
2 hours
(11.5 + 24k) hours where k is an integer. 11 and 1/2 hours.
7 and a half hours
2 hours.
It is a 3 hour time span or difference as 11 am-12 pm is 1 hour, 12 pm-1 pm is another hour, and 1pm-2 pm is a 3rd.
1 hour = 60 mins → ½ hour = ½ × 60 min = 30 min 3 hours after 11:20 am is: 11 + 3 = 14, but as this is greater than 12, subtract 12 and swap am/pm → 14 - 12 = 2, am → pm; thus 3 hours after 11:20 am is 2:20 pm. ½ hour after 2:20 pm is 30 mins after 2:20 pm→ 20 + 50 = 50 → ½ hour after 2:20 pm is 2:50 pm Thus 3½ hours after 11:20 am is 2:50 pm.
There are 4 hours from 10 am to 2 pm.
