Question

Methuselah is the oldest living human at 103 years old. How many minutes old is he?

Answer 1

The average length of a calendar year (with each year different from the next) is 525 948.77 minutes.

Therefore:

1 year : 525 948.77 minutes = 103 years : X minutes

X = (525 948.77) (103)

X = 54 172 723 minutes

103 years has 54 172 723 minutes.
