This is so last year

1 day = 24 hours

so, 7 day =1 week = 24 X 7 hours =168 hours.

now . 168 hours =1 week

so, 2016 hours is = $\frac {2016}{168}$ week = 12 weeks

$\text{1 week= 7 \times 24 hrs}$

$\large \therefore \textit{the number of weeks in 2016 hrs} = \dfrac{2016}{7 \times 24}$ $\large \boxed{12}$
