How many weeks are there in \(8!\) minutes?

 

\(\begin{array}{|rcll|} \hline 8!\ \text{min.} &=& 1*2*3*4*5*6*7*8\ \text{min.} \\ &=& 40320\ \text{min.} \\ \hline && 40320\ \text{min.} \times \dfrac{1\ \text{h}}{60\ \text{min.}} \times \dfrac{1\ \text{d}}{24\ \text{h}} \times \dfrac{1\ \text{week}}{7\ \text{d}} \\ &=& \dfrac{ 40320} {60\cdot 24\cdot 7} \ \text{weeks} \\ &=& \mathbf{4 \ \text{weeks} } \\ \hline \end{array} \)

 

8! minutes are 4 weeks.
