Explanation:
A standard decade consists of ten years, typically including eight common years and two leap years. To calculate the total number of minutes in a decade, we must first compute the minutes in common years and then add the minutes in leap years. For the common years, the calculation is 8 years × 525,600 minutes/year = 4,204,800 minutes. For the leap years, it is 2 years × 527,040 minutes/year = 1,054,080 minutes. Adding these together gives the total minutes over a decade: 4,204,800 minutes + 1,054,080 minutes = 5,258,880 minutes.
