In this question, you are asked to convert 2 weeks into microsecond. To answer this question you need to know how to convert weeks into days, hours, minutes, second, then millisecond. The calculation would be:
4fortnight x 2 (weeks/fortnight) x (7days/weeks) x (24 hours/day) x ( 60 minutes/hour) x (60 seconds/minute) x (1,000,000microsecond/second)= 4838400000000 or 4.384 [tex] 10^{12} [/tex] microsecond
