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

The correct option is 694861x.

To find the total number of seconds in $x$ weeks, $x$ days, $x$ hours, $x$ minutes, and $x$ seconds, we need to convert each unit of time into seconds and then sum them up.

Let's break down the conversions step-by-step:
1. Seconds in $x$ seconds:
This is simply $x$ seconds.

2. Seconds in $x$ minutes:
Since 1 minute = 60 seconds, $x$ minutes = $60x$ seconds.

3. Seconds in $x$ hours:
Since 1 hour = 60 minutes, and each minute has 60 seconds:
1 hour = $60\times 60=3600$ seconds.
Therefore, $x$ hours = $3600x$ seconds.

4. Seconds in $x$ days:
Since 1 day = 24 hours, and each hour has 3600 seconds:
1 day = $24\times 3600=86400$ seconds.
Therefore, $x$ days = $86400x$ seconds.

5. Seconds in $x$ weeks:
Since 1 week = 7 days, and each day has 86400 seconds:
1 week = $7\times 86400=604800$ seconds.
Therefore, $x$ weeks = $604800x$ seconds.

Now, we sum all these values to find the total number of seconds:
Total seconds = (Seconds in $x$ weeks) + (Seconds in $x$ days) + (Seconds in $x$ hours) + (Seconds in $x$ minutes) + (Seconds in $x$ seconds)
Total seconds = $604800x+86400x+3600x+60x+x$

Factoring out $x$:
Total seconds = $(604800+86400+3600+60+1)x$

Adding the numbers inside the parentheses:
$604800+86400=691200$
$691200+3600=694800$
$694800+60=694860$
$694860+1=694861$

Thus, the total number of seconds is $694861x$.
