Question

A freighter needs to travel up the Savannah River to the port, moving against the flow of the water.

If the river flows at 3 m/s relative to the shore, and the maximum speed of the freigñter relative
to the river is 7 m/s, what is the maximum velocity of the freighter relative to the shore?

Answer 1

The maximum velocity of the freighter relative to the shore is 4 m/s.

Step-by-step explanation:

To find the maximum velocity of the freighter relative to the shore, we need to consider the velocity of the river and the maximum speed of the freighter relative to the river. Since the freighter is moving against the flow of the river, we subtract the velocity of the river from the maximum speed of the freighter.

So, the maximum velocity of the freighter relative to the shore would be 7 m/s - 3 m/s = 4 m/s. Therefore, the maximum velocity of the freighter relative to the shore is 4 m/s.
