If you are 57 years old how many hours would you be?

Answer 1

It's impossible to be totally sure because we do not know which year the person was born in.

Without taking leap years into account:

Hours in a day = 24

Days in a year = 365

Hours in a year = 24 x 365 = 8760

Hours in 57 years = 8760 x 57 = 499320.

Accounting for leap years:

It is impossible to be sure exactly how many hours old this person is because it will depend on the number of leap years he has experienced, and that depends on the year in which he was born. Assuming that he was born 57 years ago this year (2010) the calculations are as follows:

His birth year = 2010 - 57 = 1953.

Number of leap years between 1953 and 2010: 14

Number of non-leap years he has lived = 57 - 14 = 43.

Hours in a day = 24

Days in a non-leap year = 365

Hours in a non-leap year = 24 x 365 = 8760

Days in a leap year = 366

Hours in a leap year = 8784

Hours in the 57 years between 1953 and 2010 = (43 x 8760) + (14 x 8784) = 376680 + 122976 = 499656
