Question
How many seconds in total are there in x weeks, x days, x hours, x minutes and x seconds?
Options
a
11580x
b
11581x
c
694860x
dAnswer
694861x
Explanation
Convert each time unit systematically down into seconds:
1 minute = 60 seconds.
1 hour = 60 × 60 = 3600 seconds.
1 day = 24 × 3600 = 86400 seconds.
1 week = 7 × 86400 = 604800 seconds.
Sum the coefficients for each variable x: Total Seconds = (604800 + 86400 + 3600 + 60 + 1)x Total Seconds = 694861x.
For cumulative unit conversions, compute the base values step-by-step and remember to include the final 1x for the baseline unit itself.
Answer: (d).
