1 minute (min) = 60 seconds (s)

1 hour (hr) = 60 minutes (min)

1 day (d) = 24 hours (hr)

Part A Convert between seconds, minutes, and hours. Write your final answer on the line.

1 4 minutes

= 240 seconds

2 180 seconds

= 3 minutes

3 5 hours

= 300 minutes

4 420 minutes

= 7 hours

5 3 days

= 72 hours

6 96 hours

= 4 days

Part B Convert each mixed time expression into the requested unit. Show your step!

7 3 minutes and 25 seconds

= 205 seconds

Workspace: (3 × 60 s) + 25 s = 180 + 25 = 205 s

8 2 hours and 45 minutes

= 165 minutes

Workspace: (2 × 60 min) + 45 min = 120 + 45 = 165 min

9 150 minutes

= 2 hr 30 min

Workspace: 150 ÷ 60 = 2 hr with 30 min remainder

10 65 hours

= 2 days 17 hr

Workspace: 65 ÷ 24 = 2 days with 17 hr remainder

1 week (wk) = 7 days (d)

1 year (yr) = 12 months (mo)

1 year = 365 days (366 leap)

Part C Convert between days, weeks, months, and years. Write your answer on the line.

11 6 weeks

= 42 days

12 56 days

= 8 weeks

13 5 years

= 60 months

14 84 months

= 7 years

15 9 weeks

= 63 days

16 108 months

= 9 years

Part D Convert each mixed calendar expression into the designated units.

17 4 weeks and 5 days

= 33 days

Workspace: (4 × 7 days) + 5 days = 28 + 5 = 33 days

18 3 years and 8 months

= 44 months

Workspace: (3 × 12 mo) + 8 mo = 36 + 8 = 44 months

19 45 days

= 6 wk 3 days

Workspace: 45 ÷ 7 = 6 wk with 3 days remainder

20 50 months

= 4 yrs 2 mos

Workspace: 50 ÷ 12 = 4 yrs with 2 mos remainder
