We invite you to solve the English version of the RTSdécouverte monthly problem:
Crossing a river
A family needs to cross a river and there is only one small boat. The father weighs 80 kg, the mother 75 kg, the son 40 kg, the daughter 38 kg and the small dog about 5 kg. The catch is that the boat can carry a maximum load of 80 kg. How can the whole family cross the river? (No-one can swim!)
