mr. t has been dating his girlfriend for one year, nine months, and six days. how many hours has mr. t been in a relationship? (assume mr. t put “in a relationship” on facebook the second they started dating)
Answer
Explanation:
Step1: Convert years to hours
$1$ year has $365$ days and $1$ day has $24$ hours, so $1\times365\times24 = 8760$ hours.
Step2: Convert months to hours
Assume an average month has $30$ days. $9$ months have $9\times30\times24=6480$ hours.
Step3: Convert days to hours
$6$ days have $6\times24 = 144$ hours.
Step4: Sum up
$8760 + 6480+144=15384$ hours.
Answer:
$15384$
