Let's solve each subtraction problem step by step. These are mixed unit subtractions involving time (hours, minutes, seconds), weight (pounds, ounces), and length (feet, inches). We'll handle each one carefully, borrowing when necessary.

1. Time: 58 hr 42 min – 21 hr 57 min

We can't subtract 57 min from 42 min, so borrow 1 hour (60 minutes) from 58 hours:

- 58 hr 42 min = 57 hr + 60 min + 42 min = 57 hr 102 min
- Now subtract:
- 57 hr 102 min – 21 hr 57 min = (57–21) hr + (102–57) min = 36 hr 45 min

✔ Answer: 36 hr 45 min

---

2. Weight: 89 lb 03 oz – 57 lb 08 oz

Can't subtract 8 oz from 3 oz → borrow 1 lb (16 oz):

- 89 lb 3 oz = 88 lb + 16 oz + 3 oz = 88 lb 19 oz
- Subtract:
- 88 lb 19 oz – 57 lb 8 oz = (88–57) lb + (19–8) oz = 31 lb 11 oz

✔ Answer: 31 lb 11 oz

---

3. Time: 56 min 51 sec – 54 min 56 sec

Can't subtract 56 sec from 51 sec → borrow 1 minute (60 seconds):

- 56 min 51 sec = 55 min + 60 sec + 51 sec = 55 min 111 sec
- Subtract:
- 55 min 111 sec – 54 min 56 sec = (55–54) min + (111–56) sec = 1 min 55 sec

✔ Answer: 1 min 55 sec

---

4. Weight: 82 lb 10 oz – 77 lb 14 oz

Can't subtract 14 oz from 10 oz → borrow 1 lb (16 oz):

- 82 lb 10 oz = 81 lb + 16 oz + 10 oz = 81 lb 26 oz
- Subtract:
- 81 lb 26 oz – 77 lb 14 oz = (81–77) lb + (26–14) oz = 4 lb 12 oz

✔ Answer: 4 lb 12 oz

---

5. Length: 46 ft 05 in – 22 ft 08 in

Can't subtract 8 in from 5 in → borrow 1 ft (12 in):

- 46 ft 5 in = 45 ft + 12 in + 5 in = 45 ft 17 in
- Subtract:
- 45 ft 17 in – 22 ft 8 in = (45–22) ft + (17–8) in = 23 ft 9 in

✔ Answer: 23 ft 9 in

---

6. Time: 48 min 30 sec – 44 min 42 sec

Can't subtract 42 sec from 30 sec → borrow 1 min (60 sec):

- 48 min 30 sec = 47 min + 60 sec + 30 sec = 47 min 90 sec
- Subtract:
- 47 min 90 sec – 44 min 42 sec = (47–44) min + (90–42) sec = 3 min 48 sec

✔ Answer: 3 min 48 sec

---

7. Length: 39 ft 02 in – 31 ft 07 in

Can't subtract 7 in from 2 in → borrow 1 ft (12 in):

- 39 ft 2 in = 38 ft + 12 in + 2 in = 38 ft 14 in
- Subtract:
- 38 ft 14 in – 31 ft 7 in = (38–31) ft + (14–7) in = 7 ft 7 in

✔ Answer: 7 ft 7 in

---

8. Time: 76 hr 49 min – 57 hr 56 min

Can't subtract 56 min from 49 min → borrow 1 hr (60 min):

- 76 hr 49 min = 75 hr + 60 min + 49 min = 75 hr 109 min
- Subtract:
- 75 hr 109 min – 57 hr 56 min = (75–57) hr + (109–56) min = 18 hr 53 min

✔ Answer: 18 hr 53 min

---

9. Time: 56 hr 48 min – 43 hr 56 min

Can't subtract 56 min from 48 min → borrow 1 hr:

- 56 hr 48 min = 55 hr + 60 min + 48 min = 55 hr 108 min
- Subtract:
- 55 hr 108 min – 43 hr 56 min = (55–43) hr + (108–56) min = 12 hr 52 min

✔ Answer: 12 hr 52 min

---

10. Length: 32 ft 01 in – 31 ft 11 in

Can't subtract 11 in from 1 in → borrow 1 ft:

- 32 ft 1 in = 31 ft + 12 in + 1 in = 31 ft 13 in
- Subtract:
- 31 ft 13 in – 31 ft 11 in = (31–31) ft + (13–11) in = 0 ft 2 in or simply 2 in

✔ Answer: 2 in

---

11. Weight: 64 lb 07 oz – 42 lb 08 oz

Can't subtract 8 oz from 7 oz → borrow 1 lb:

- 64 lb 7 oz = 63 lb + 16 oz + 7 oz = 63 lb 23 oz
- Subtract:
- 63 lb 23 oz – 42 lb 8 oz = (63–42) lb + (23–8) oz = 21 lb 15 oz

✔ Answer: 21 lb 15 oz

---

12. Time: 55 min 16 sec – 37 min 21 sec

Can't subtract 21 sec from 16 sec → borrow 1 min:

- 55 min 16 sec = 54 min + 60 sec + 16 sec = 54 min 76 sec
- Subtract:
- 54 min 76 sec – 37 min 21 sec = (54–37) min + (76–21) sec = 17 min 55 sec

✔ Answer: 17 min 55 sec

---

13. Length: 46 ft 08 in – 38 ft 11 in

Can't subtract 11 in from 8 in → borrow 1 ft:

- 46 ft 8 in = 45 ft + 12 in + 8 in = 45 ft 20 in
- Subtract:
- 45 ft 20 in – 38 ft 11 in = (45–38) ft + (20–11) in = 7 ft 9 in

✔ Answer: 7 ft 9 in

---

14. Time: 82 hr 06 min – 70 hr 07 min

Can't subtract 7 min from 6 min → borrow 1 hr:

- 82 hr 6 min = 81 hr + 60 min + 6 min = 81 hr 66 min
- Subtract:
- 81 hr 66 min – 70 hr 7 min = (81–70) hr + (66–7) min = 11 hr 59 min

✔ Answer: 11 hr 59 min

15. Weight: 86 lb 11 oz – 73 lb 14 oz

Can't subtract 14 oz from 11 oz → borrow 1 lb:

- 86 lb 11 oz = 85 lb + 16 oz + 11 oz = 85 lb 27 oz
- Subtract:
- 85 lb 27 oz – 73 lb 14 oz = (85–73) lb + (27–14) oz = 12 lb 13 oz

✔ Answer: 12 lb 13 oz
