Final answer:
The differences in hours and minutes between the given pairs of times are calculated by subtracting the earlier time from the later time.
Step-by-step explanation:
To find the difference between two times, we need to subtract the earlier time from the later time. Let's calculate the differences for each given pair of times:
- a) 12:35 to 15:20:
15:20 - 12:35 = 2 hours and 45 minutes - b) 10:15 to 13:05:
13:05 - 10:15 = 2 hours and 50 minutes - c) 4:30am to 6:50am:
6:50 - 4:30 = 2 hours and 20 minutes - d) 9:55am to 1:15pm:
1:15 - 9:55 = 3 hours and 20 minutes
