**Burning Barn Problem**
A scout troop is camping in tents 40 metres from the river. They notice a barn that is 120 metres downstream, but 60 metres from the river. At what point along the river should they head towards to fill their buckets to put the fire out? Can you develop a model using Cabri Geometry to solve the problem, and use a spreadsheet to get a more accurate answer?
