Answer: 8 4/5 weeks
Explanation:
Let the length of entire trip = 1
Length of trip already traveled = 5/6
Time taken to cover 5/6 length = 7 1/3 weeks
Then;
Length of trip left to cover = (1 - 5/6) = 1/6
Therefore, if (5/6) takes 22/3 weeks
(5/6) = 22/3
1/6 length of the trip = (22/3) ÷ 5
= (22 /3) × (1 / 5)
= 22/ 15 = 1 7/15 weeks
Therefore, length of entire trip ;
(1 / 6) * 6 --------> (22 / 15) × 6
Full length of trip = 132 / 15
Full length of trip = 8 12/15
= 8 4/5 weeks
