A man can row a boat at a speed of 2metres per second . The man set out to row the boat in a river from A to B. The water in the river flows 0.8metres per second in the opposite direction.Determine the velocity of the boat through the water.
You already said the speed of the boat through the water was 2 m/s
The speed over the land is 2-.8 = 1.2 m/s
To determine the velocity of the boat through the water, you need to consider the relative velocities of the boat and the river.
The velocity of the boat through the water can be calculated by subtracting the velocity of the river from the velocity of the boat.
Given:
Velocity of the boat (boat speed) = 2 m/s
Velocity of the river (river speed) = 0.8 m/s (opposite direction)
To find the velocity of the boat through the water, you subtract the velocity of the river from the velocity of the boat:
Velocity of the boat through the water = Boat Speed - River Speed
Velocity of the boat through the water = 2 m/s - 0.8 m/s = 1.2 m/s
Therefore, the velocity of the boat through the water is 1.2 m/s.
