Which method should he choose? A crofter has to get to his herd of sheep quickly as he has been told they are being attacked by a dog. His sheep are on the other side of a steep hill. He can run over the hill (3 miles) at 4 miles an hour or take his tractor via an old dirt track which is 5 miles at an average of 6 miles an hour or he can drive his car along a very narrow winding road but this is 14 miles and he can only go at 18 miles an hour on average.
A is the best answer to this question. It should be remembered that the crofter would need to get to his sheep at the soonest possible time. The tractor and the car may be faster but it would take more effort to drive the car and the tractor on the road.
There are some people who think that the crofter is someone who is only considered to be a hippie probably because their way of living is not the same with what people may expect. It is important that they keep track of all the details regarding their farm so that they can live the way that they want to.
