Answer:
If 1 mo = 30 days: 13 yr + 5 mo + 5 days
If 1 yr = 365 days: 13 yr + 3 mo + 7days
Explanation:
The two conversion factors are incompatible, so I will so both calculations.
1. Assume that a month has 30 days.
Age = 6 973 920 min Convert to hours
Age = 6 973 920 min × (1 h/60 min)
Age = 116 232 h Convert to days
Age = 116 232 h × (1 day/24 h)
Age = 4843 days Convert to months
Age = 4843 days × (1 mo/30 days)
Age = 161¹³/₃₀ mo
Age = 161 mo 13 days Convert months to years
Age = 161 mo × (1 yr/12 mo) + 13 days
Age = 13⁵/₁₂ yr + 13 days
Age = 13 yr + 5 mo + 5 days
Mia is 13 years, five months, and five days old.
2. Assume that a year has 365 days
Age = 4843 days Convert to years
Age = 4843 days × (1 yr/365 days)
Age = 13.2685 yr Convert the decimal part to months
Months = 0.2685 yr × (12 mo/1 yr)
Months = 3.222 mo Convert the decimal portion to days
Days = 0.222 mo × (30 da/1 mo)
Days = 7
Age = 13 yr + 3 mo + 7 days
Mia is 13 years, three months, and seven days old.
