"Where is it easier to ride a bicycle: to the river or back?" - a rhetorical question, often asked in the forums.
The question itself is laconic, but there can be as many answers as there are, from banal to very original ones.
The respondent, who is completely absent asSense of humor, and imagination, will say: "Finally, to the river." And from a logical point of view it will be absolutely right. After all, to the river you go downhill, and back - uphill. And going downhill is always easier.
More corrosive, but continuingGuided solely by the logic of the respondent will add: everything depends on the additional conditions. The road to the river can consist of sections with different elevations. It is easier to go by one of them, for others it is more difficult. And only the last of the sections will have to go downhill. And the road back will be different only in that these areas will have to be overcome in reverse order. The wind can also blow in different directions. If it is strong enough, and when driving to the river it is necessary to go against the wind, and back - to the wind, then going back can be easier, despite the need to move uphill.
Much depends also on what you went toRiver. If you swim, ride a boat, then back you will go tired. And if you sunbathe or catch fish - rested. Although, if you have caught a lot of fish, it can be difficult to carry it. And, maybe, to the river you went with a backpack full of sandwiches, and back - light. It is also unknown what you did before riding a bicycle. If they chopped wood, and then rested on the river, it would be easier to go back to the river than to the river.
Answering this question, it is often forgotten thatYou can ride a bike and a passenger sitting on the trunk. In this case, going both to the river and back will be equally easy. Equally important is the availability of incentives for the trip. Perhaps the river is waiting for you, and maybe she is waiting for your arrival with a fish caught at home. Finally, the question does not say a word about whether a cyclist will go to the river and back by the same route or to the river by one, and back - to another.
So there can be many factors, their combinations -Even more, and all this in one way or another determines the answer to this seemingly uncomplicated question. Specialists in information theory in such cases say that the question is not completely formulated, and additional information is needed to answer it.
