Пусть S(км)-расстояние между пунктами А и B

Течение имеет направления от  пункта А к пункту B (t1<t2)

Скорость по течению равна сумме собственной скорости катера и скорости течения

V1=Vc+Vтеч

Скорость против течения равна разности собственной скорости катера и скорости течения

V2=Vc-Vтеч

V1*t1=S

V2*t2=S

Мотор выключили,значит собственная скорость катера равна 0.

V3=Vтеч

V3*t3=S

(Vc+Vтеч)*t1=S

(Vc-Vтеч)*t2=S

(Vc+Vтеч)*t1=(Vc-Vтеч)*t2

Vc*t1+Vтеч*t1=Vc*t2-Vтеч*t2

Vс*(t2-t1)=Vтеч(t1+t2)

Vc=Vтеч*()

Vтеч*(1+)*t1=S

Vтеч*()*t1=S

Vтеч*()=S

Vтеч*t3=S

t3=

t3=(2*3*6/(6-3))ч=12ч

ответ:t3=12ч
