Question

Mia is 7.01280 x 10^6 minutes old. Convert her age to more appropriate units using years, months and days. Assume a year has 365 days and a month has 30 days.

Answer 1

Mia is 13 years 4 months and 5 days old

Answer 2

Answer:

The age of Mia is 13 year 6 months 122.64 days old.

Step-by-step explanation:

Given : Mia is $7.01280\times 10^6$ minutes old.

To find : Convert her age to more appropriate units using years, months and days. Assume a year has 365 days and a month has 30 days.

Solution :

Mia is $7.01280\times 10^6$ minutes old.

Converting minutes into year month and days.

We know,

There are 60 or $6\times 10$ minutes in an hour.

There are 24 or $2.4\times 10$ hour in an day.

There are 30 or $3\times 10$ day in a month.

There are 12 or $1.2\times 10$ month in a year.

For conversion divide all by given unit,

$n=\frac{7.01280\times 10^6}{(6\times 10)(2.4\times 10)(3\times 10)(1.2\times 10)}$

$n=\frac{7.01280}{6\times 2.4\times 3\times 1.2}\times 10^{6-1-1-1-1}$

$n=0.13528\times 10^{2}$

$n=13.528$

i.e. Mia is 13.528 years old.

Now, 0.528 years into months is $0.528\times 12=6.336$

i.e. Mia is 13 year 6.336  months old.

Now, 0.336 months into days is $0.336\times 365=122.64$

i.e.  Mia is 13 year 6 months 122.64 days old.

Therefore, The age of Mia is 13 year 6 months 122.64 days old.
