Question

1. joyanna is 14 years old. how many minutes is this? (three of these years were leap years.)

126, 960 minutes
7, 358, 400 minutes
7, 362, 720 minutes
18, 396, 000 minutes

Explanation:

Step1: Calculate days in non - leap years

A non - leap year has 365 days. The number of non - leap years is \(14 - 3=11\). So the total number of days from non - leap years is \(11\times365 = 4015\) days.

Step2: Calculate days in leap years

A leap year has 366 days. The number of leap years is 3. So the total number of days from leap years is \(3\times366=1098\) days.

Step3: Calculate total days

The total number of days in 14 years is \(4015 + 1098=5113\) days.

Step4: Calculate total hours

Since there are 24 hours in a day, the total number of hours is \(5113\times24 = 122712\) hours.

Step5: Calculate total minutes

Since there are 60 minutes in an hour, the total number of minutes is \(122712\times60=7362720\) minutes.

Answer:

7,362,720 minutes
