A boat has a speed of 10 m s in still water With this boat a person wants to cross the river from point A There is another point B on the other bank as shown The river velocity is 5 m s and width is 100 m B A If velocity of boat relative to water is perpendicular to the river bank then it reaches 50 m upstream of B B If velocity of boat relative to water is along AB it reaches 50 2 m downstream of B C Minimum time to cross the river is 10 s D If the river has to be crossed along the shortest path boat velocity relative to river should make an angle of 120 with river velocity
