Will it take longer to swim to a point 100 yards up-stream and back,
or to a point 100 yards across-stream and back?
Let us take a numerical example.
Suppose the swimmer's speed is 50 yards a minute in still water, and the current is 30 yards a minute.
Thus the speed against the current is 20, and with the current 80 yards a minute.
Going across-stream the swimmer must aim at a point E above the point B where he wishes to arrive, so that OE represents his distance travelled in still water, EB the amount he has drifted down. These must be in the ratio 50 to 30, and we then know from the right-angled triangle OBE that OB will correspond to 40. Since OB is 100yards, OE is 125yards.
You must see the attached file above or picture
Which is faster? Why?
You Orbian? prove it!
I don't give u any answer, U Orbian? get me the answer!

the hint is inherent in this paragraph too!

이 점 1백야드 스트림 까지 다시 수영 하는 데 시간이 더 걸릴 것입니다,
또는 포인트 1백야드 스트림 에서 다시 에?
우리가 계산능력 예시를 보자.
가정수영 의 속도는 50야드 여전히 물에 1분이며, 현재 30 야드 1분입니다.
따라서, 현재속도에 대해 20이고, 현재 80야드와 1분.
어느 것이 더 빠르다? 왜?
당신 Orbian? 그것을 증명!
나는 U 어떤 대답, U Orbian 를 주지 않는다? 나에게 답을 얻을!
hey guy your translation is good ㅠㅠ and close to something right but not perfect ㅠㅠ
uh... i don't mean translation please catch the point!
50으로 왕복하는 거랑
갈때 20 올때 80인거랑은
전자가 빠르겠다요
