Captain Tuan, Hoban, Orrin, Kentari and Anshu decided to go sailing to other worlds for the vacation. During the time on the ocean, they had a bad storm and broke their ship into pieces. Fortunally, all of them survive were able to get to an island nearby. A small boat was with them also.

After a few days, Hoban located a nearby bigger island where there are a lot of fruits to eat and wood to build a ship to go back home. The problem is only maximum two of them can fit in the boat so they have to travel back and forth to get all of them to the other island.

If Hoban sails alone, it would take him 1 day to get to the next island. For Captain Tuan, it's 2 days. For Kentari, it's 5 days. For Orrin, it's 10 days. And for Anshu, it's 10 days. If two of them sail together, the time to travel is the time of slower one (the slower one drag down the speed).

Question: What is the shortest time to take all of them to the other island?

Prize: Finding Cyodrakes Gaze

23 days:
H & T - 2 days
T - 2 days
o & a - 10
h - 1
h & k -5
h - 1
h & t -2

I believe thats right.. unless no one needs to go back with the boat ?

The least amount of days is 23 days.

They would have to sail in this order to have the least.

Captain Tuan and Hoban sail first, That makes it 2 days. Hoban sails back that makes it 3 days. Orrin and Anshu then sail next making it 13 days, and Captain Tuan sails back making it 15 days. Then Hoban and Kentari sail which makes it 20 days, Hoban sails back making it 21 days. Hoban and Captain Tuan sail to the island one final time to make it 23 days.

Both super and Lani's answers are correct. Since super answered first (Lani edited her answer), he won the prize and got 1 point for the ladder.
