First, calculate the distance traveled in the first two seconds using the graph. The starting distance is 100 m. The distance at the two second mark is about 18 m. 100 - 18 = 82 m. Next use the speed formula, v = d/t to calculate the average speed: 82m/2s = 41m/s.
The villagers have to find a way to do something. They will have to find another way to do that thing. It is like saying there is another way to skin a cat or milk a cow
