Four Adventurers Challenge

01 Mar Four Adventurers Challenge

Four adventurers (Alex, Brook, Chris and Dusty) need to cross a river in a small canoe.
The canoe can only carry 100kg.
Alex weighs 90kg, Brook weighs 80kg, Chris weighs 60kg and Dusty weighs 40 kg, and they have 20kg of supplies.
How do they get across?

A solution from Keira in Year 6

Chris and Dusty cross first
Dusty returns with the boat
Brook and the supplies then cross
Chris returns with the boat
Chris and dusty then cross
Dusty returns with the boat
Alex crosses
Chris returns with the boat
Finally Chris and Dusty cross the river

Well Done!
