Someone swims across the river. The swimming speed in still water is 12% of the flow velocity of the river
Because the water velocity is less than theSwim across the river  because the water velocity is less than the water velocity water velocity, it is known that when the direction of the combined velocity is perpendicular to the direction of the static water velocity, the displacement to the opposite bank is the shortest. The included angle between the swimming direction and the upstream bank is , Then cos = 12. so = 60 . Therefore, B is correct and a, C and D are wrong. Therefore, B is selected

As shown in the figure, the combined speed of 1.4 and 0.8 is the speed indicated by the diagonal: v = √ (1.4 1.4-0.8 0.8) = 1.15m/s t = s/v = 70/1.15 = 60.87s angle: form an angle with the river bank towards the upstream, arccos0.57 unknown... The river has no boats or bridges. So Swim across the river  because the water velocity is less than the water velocityhe swam across the river in the morning for only an hour
You lost his wallet, went back to find the key, and went back again. The young man was careless, so he fell asleep on the bank. A beautiful woman swam around with the beautiful woman in the river.

Let's see how to understand the topic. Here, "two and a half hours" can be understood as two and a half hours, so he will use one hour. If it is understood as two and a half hours, that is, two hours plus half an hour, so the answers upstairs are not all rightWhat does it mean to cross the river by boat or by swimming
What do you mean by crossing the river or swimming across the river? It depends on what you said earlier. Now I can explain to you that people who cross the river by boat will not get their clothes and shoes wet. If you swim, people will get wet. From your words, I can only explain it this way.
