How many seconds in total are there in x weeks, x days, x hours, x minutes and x seconds?

Correct Answer: (D) 694861x

Converting each time component into seconds: 1 week $= 7$$\times$ 24 $\times$ 3600 = 604,800$\text{ s}$; 1 day $= 24$$\times$ 3600 = 86,400$\text{ s}$; 1 hour $= 3,600$$\text{ s}$; 1 minute $= 60$$\text{ s}$; and 1 second $= 1$$\text{ s}$. Summing these together gives total seconds $= x(604800 + 86400 + 3600 + 60 + 1) = 694,861x$.
