Question 1: Convert minutes to seconds
We multiply the number of minutes by 60.
| Problem | Calculation | Answer |
|--------|-------------|--------|
| 1 min = ___ s | 1 × 60 = 60 |
60 s |
| 2 min = ___ s | 2 × 60 = 120 |
120 s |
| 3 min = ___ s | 3 × 60 = 180 |
180 s |
| 4 min = ___ s | 4 × 60 = 240 |
240 s |
| 5 min = ___ s | 5 × 60 = 300 |
300 s |
| 6 min = ___ s | 6 × 60 = 360 |
360 s |
| 7 min = ___ s | 7 × 60 = 420 |
420 s |
| 8 min = ___ s | 8 × 60 = 480 |
480 s |
| 9 min = ___ s | 9 × 60 = 540 |
540 s |
| 10 min = ___ s | 10 × 60 = 600 |
600 s |
✔ Answers:
- 1 min =
60 s
- 2 min =
120 s
- 3 min =
180 s
- 4 min =
240 s
- 5 min =
300 s
- 6 min =
360 s
- 7 min =
420 s
- 8 min =
480 s
- 9 min =
540 s
- 10 min =
600 s

Question 2: Convert minutes and seconds to seconds
We convert minutes to seconds, then add the extra seconds.
(a) 1 min 10 s
= (1 × 60) s + 10 s
= 60 s + 10 s
=
70 s
(b) 2 min 37 s
= (2 × 60) s + 37 s
= 120 s + 37 s
=
157 s
(c) 5 min 4 s
= (5 × 60) + 4 = 300 + 4 =
304 s
(d) 6 min 55 s
= (6 × 60) + 55 = 360 + 55 =
415 s
(e) 3 min 28 s
= (3 × 60) + 28 = 180 + 28 =
208 s
(f) 7 min 10 s
= (7 × 60) + 10 = 420 + 10 =
430 s
✔ Answers:
- (a) 70 s
- (b) 157 s
- (c) 304 s
- (d) 415 s
- (e) 208 s
- (f) 430 s

Question 3: Convert seconds to minutes
We divide seconds by 60 to get minutes.
(a) 120 s = ___ min
120 ÷ 60 =
2 min
(b) 360 s = ___ min
360 ÷ 60 =
6 min
(c) 180 s = ___ min
180 ÷ 60 =
3 min
(d) 480 s = ___ min
480 ÷ 60 =
8 min
✔ Answers:
- (a) 2 min
- (b) 6 min
- (c) 3 min
- (d) 8 min

Question 4: Convert seconds into minutes and seconds
We divide the total seconds by 60. The
quotient is minutes, and the
remainder is seconds.
(a) 85 s = 60 s + ___ s
85 – 60 = 25 → So, 60 s + 25 s
=
1 min 25 s
(b) 139 s = 120 s + ___ s
139 – 120 = 19 → So, 120 s + 19 s
=
2 min 19 s
(c) 362 s = ___ min ___ s
362 ÷ 60 = 6 remainder 2
→ 6 × 60 = 360, so 362 – 360 = 2
=
6 min 2 s
(d) 510 s = ___ min ___ s
510 ÷ 60 = 8 remainder 30
→ 8 × 60 = 480, 510 – 480 = 30
=
8 min 30 s
(e) 278 s = ___ min ___ s
278 ÷ 60 = 4 remainder 38
→ 4 × 60 = 240, 278 – 240 = 38
=
4 min 38 s
(f) 191 s = ___ min ___ s
191 ÷ 60 = 3 remainder 11
→ 3 × 60 = 180, 191 – 180 = 11
=
3 min 11 s
✔ Answers:
- (a) 60 s +
25 s =
1 min 25 s
- (b) 120 s +
19 s =
2 min 19 s
- (c)
6 min 2 s
- (d)
8 min 30 s
- (e)
4 min 38 s
- (f)
3 min 11 s
