3. A boat, propalled so as to travel with a speed of 050 m/s in still water,
moves directly across a river that is 60m wide The river flows with speed
of 30 m/(o) At what angle relative to the straight-across direction
must the boat be pointed? (b) How long does it take the boat to
Cross the river?​

  1. Step-by-step explanation:

    tanA = 0.3/0.5 = 0.6

    A = 31o

    D = 60/cos31 = 70 m.

    V = 70/cos31 = 0.583 m/s

    D = V*t = 70 m.

    0.583*t = 70

    t = 120.1 s.

    I think it’s helpful
