18 hours, 20 minutes + 6 hours, 40 minutes
= 25 hours

1 week = 24 * 7 hours

Required Fraction = 25 / 24*7 = 25 / 168

Hence, B.

Summation of 18 hours, 20 minutes 6 hours, 40 minutes is equivalent to :
18 + 6 + 1/3(20/60 hours) + 2/3(40/60 hours) = 24+1 = 25 hours.
Hours in a week = 24*7 = 168
Hence, 25/168, B.

18 hours 20 minutes + 6 hours 40 minutes = 24 hours 60 minutes = 25 hours

Since 1 day = 24 hours, then 25 hours = 25/24 days, which is (25/24)/7 weeks, or 25/168 weeks.
