A swimmer can swim at 3 m/s in still water. If the river flows at 2 m/s, what is the swimmer's speed relative to the bank when swimming upstream?

A swimmer can swim at 3 m/s in still water. If the river flows at 2 m/s, what is the swimmer's speed relative to the bank when swimming upstream?

Step 1: Understand that the swimmer's speed in still water is 3 m/s.
Step 2: Know that the river flows at a speed of 2 m/s.
Step 3: When swimming upstream, the swimmer is swimming against the flow of the river.
Step 4: To find the swimmer's speed relative to the bank, subtract the speed of the river from the swimmer's speed.
Step 5: Perform the calculation: 3 m/s (swimmer's speed) - 2 m/s (river's speed) = 1 m/s.
Step 6: Conclude that the swimmer's speed relative to the bank when swimming upstream is 1 m/s.

Relative Speed – Understanding how to calculate the speed of an object in relation to another moving object.
Vector Addition – Applying vector subtraction when dealing with opposing directions (swimmer vs. river current).
