Mia is 6.93648 x 10^6 minutes old. Convert her age to more appropriate units using years,
miskamm [114]

For this case we have the following expression in units of minutes:

6.93648 * 10 ^ 6

As the exponent is positive we run the decimal six spaces to the right:

6,936,480 \ min

We have 1 hour has 60 min, then:

\frac {6,936,480} {60} = 115,608 \ hours

On the other hand, we have one day has 24 hours.

\frac {115,608} {24} = 4,817 \ days

Likewise, a month has 30 days:

\frac {4817} {30} = 160.57 \ months

Also, one year has 365 days:

\frac {4817} {365} = 13.20 \ years

Finally, Mia is 13 years old equivalent to 160 months, which is equal to 4817 days.

ANswer:

Mia is 13 years old equivalent to 160 months, which is equal to 4817 days.
