Question

- The normal duration of I.Sc. Physics practical period in
Indian colleges is 100 minutes. Express this period in
microcenturies. 1 microcentury = 10 x 100 years. How
many microcenturies did you sleep yesterday?​

Answer 1

1 hr = 60 mins

60 mins = 1hr

1mins = 1/60 hr

100 mins = 1/60*100 hrs

= 5/3 hrs

= 1 2/3 hrs

1 year = 8760 hours

8760 hrs = 1 year

5/3 hrs = 1/8760 *3/5 years

= 1/14600 years

1 microcentury = 1000 years

1/14600 years = 1/1000*14600 microcenturies

= 14.6 microcenturies
