Answer 1

Answer:

1. 2450 min
2. 7576 sec
3. 28days 16 hours
4. 52 weeks 1 day
5. 13 days 34 hours

Step-by-step explanation:

1. we know, 60m= 1h and 24h= 1day

=(3×24)h + (15×60)m + 30min

= (72×60)min + 900min +30min

=1520 + 900 + 30 = 2450mins

2. we know , 1h= 60 mins and 1min= 60sec

=(3×60)mins + (36×60)sec + 16 sec

= (90×60)sec + 2160 s + 16s

= 5400 + 2160 + 16 = 7576 secs

3.we know, 24h= 1day

= (688÷24) days

= 28 days 16hours

4. we know, 1 week = 7 days

= (365÷7) weeks

= 52 weeks 1 day

5. we know, 1h=60m and 1 min= 60s

= (814÷60)h

=13 days 34h
