Q: 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?

Solution: Speed relative to bank = Speed of swimmer - Speed of river = 3 m/s - 2 m/s = 1 m/s.

Steps: 6

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.
