Question: A person can swim at a speed of 5 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the person swimming upstream?

Options:

3 km/h
5 km/h
7 km/h
9 km/h

Correct Answer: 3 km/h

Solution:

Speed upstream = Speed in still water - Speed of current = 5 - 2 = 3 km/h.

Questions & Step-by-Step Solutions

A person can swim at a speed of 5 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the person swimming upstream?

Step 1: Understand that the person can swim at a speed of 5 km/h in still water.
Step 2: Know that there is a current that flows at a speed of 2 km/h.
Step 3: When swimming upstream, the current works against the swimmer's speed.
Step 4: To find the speed of the person swimming upstream, subtract the speed of the current from the speed in still water.
Step 5: Calculate the speed upstream: 5 km/h (swimming speed) - 2 km/h (current speed) = 3 km/h.
Step 6: Conclude that the speed of the person swimming upstream is 3 km/h.
