Explanation

To find the total number of seconds, we convert each given time unit into seconds and sum them up. 1. Seconds in x weeks: 1 week = 7 days 1 day = 24 hours 1 hour = 60 minutes 1 minute = 60 seconds So, 1 week = 7 * 24 * 60 * 60 = 604800 seconds. x weeks = 604800x seconds. 2. Seconds in x days: 1 day = 24 * 60 * 60 = 86400 seconds. x days = 86400x seconds. 3. Seconds in x hours: 1 hour = 60 * 60 = 3600 seconds. x hours = 3600x seconds. 4. Seconds in x minutes: 1 minute = 60 seconds. x minutes = 60x seconds. 5. Seconds in x seconds: x seconds = x 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 Total seconds = (604800 + 86400 + 3600 + 60 + 1)x Total seconds = 694861x. Analyzing the options: A) 11580 x - Incorrect. B) 11581 x - Incorrect. C) 694860 x - Incorrect (misses the final 'x seconds'). D) 694861 x - Correct. The final answer is D) 694861 x.
