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

• x weeks = (7 \times 24 \times 60 \times 60,x = 604800x) seconds.
• x days = (24 \times 60 \times 60,x = 86400x) seconds.
• x hours = (60 \times 60,x = 3600x) seconds.
• x minutes = (60x) seconds.
• x seconds = (x) seconds.

Total = (604800x + 86400x + 3600x + 60x + x = 694861x). Hence, (d) 694861x is correct.
