Aboat's motor propels the boat through the water at 3m/s. the driver of the boat wants to go in a straight ine directly across the river, but there is a 1m/s current flowing perpendicular to the direction in which the driver wants to go

Direction of boat's motion = 109.52°

In the question,

Speed of the boat, v = 3 m/s

Speed of the current, c = 1 m/s

The speed of the current is perpendicular to the resultant direction of the motion of the boat, R.

So,

In the triangle, using the Pythagoras Theorem,

So,

Therefore, the Resultant speed of the Boat is given by,

R = 2.82 m/s

And,

Direction of the motion of the Boat is given by,

So,

Angle made by the Boat with the Horizontal is,

θ = 90 + 19.52 = 109.52°

Therefore, the Boat should be moving at 109.52° with the horizontal.

(75°f − 32) × 5/9 = 23.889°c
