Let’s solve each problem step by step. We’ll add the hours and minutes separately, and if the minutes go over 60, we’ll convert the extra minutes into hours.
---
1) 5hr 15min + 3hr 20min
Hours: 5 + 3 =
8 hr
Minutes: 15 + 20 =
35 min
→ Answer:
8 hr 35 min
---
2) 6hr 25min + 4hr 30min
Hours: 6 + 4 =
10 hr
Minutes: 25 + 30 =
55 min
→ Answer:
10 hr 55 min
---
3) 4hr 06min + 2hr 36min
Hours: 4 + 2 =
6 hr
Minutes: 6 + 36 =
42 min
→ Answer:
6 hr 42 min
---
4) 1hr 19min + 10hr 38min
Hours: 1 + 10 =
11 hr
Minutes: 19 + 38 =
57 min
→ Answer:
11 hr 57 min
---
5) 2hr 45min + 3hr 30min
Hours: 2 + 3 =
5 hr
Minutes: 45 + 30 =
75 min → That’s more than 60!
75 min = 60 min + 15 min =
1 hr 15 min
So total hours: 5 + 1 =
6 hr, and minutes:
15 min
→ Answer:
6 hr 15 min
---
6) 1hr 25min + 7hr 55min
Hours: 1 + 7 =
8 hr
Minutes: 25 + 55 =
80 min → More than 60!
80 min = 60 min + 20 min =
1 hr 20 min
Total hours: 8 + 1 =
9 hr, minutes:
20 min
→ Answer:
9 hr 20 min
---
7) 3hr 55min + 6hr 48min
Hours: 3 + 6 =
9 hr
Minutes: 55 + 48 =
103 min → Way over 60!
103 ÷ 60 = 1 hour with remainder 43 → so
1 hr 43 min
Total hours: 9 + 1 =
10 hr, minutes:
43 min
→ Answer:
10 hr 43 min
---
8) 8hr 47min + 3hr 58min
Hours: 8 + 3 =
11 hr
Minutes: 47 + 58 =
105 min → Over 60!
105 ÷ 60 = 1 hour with remainder 45 → so
1 hr 45 min
Total hours: 11 + 1 =
12 hr, minutes:
45 min
→ Answer:
12 hr 45 min
---
Final Answer:
1) 8 hr 35 min
2) 10 hr 55 min
3) 6 hr 42 min
4) 11 hr 57 min
5) 6 hr 15 min
6) 9 hr 20 min
7) 10 hr 43 min
8) 12 hr 45 min
