Question: A boat can travel at a speed of 10 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the boat upstream?

Options:

Correct Answer: 8 km/h

Solution:

Speed upstream = Speed in still water - Speed of current = 10 - 2 = 8 km/h.

A boat can travel at a speed of 10 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the boat upstream?

A boat can travel at a speed of 10 km/h in still water. If the speed of the current is 2 km/h, what is the speed of the boat upstream?

Step 1: Understand that the boat's speed in still water is 10 km/h.
Step 2: Know that the current of the water is moving at 2 km/h.
Step 3: When the boat is going upstream, it is moving against the current.
Step 4: To find the speed of the boat upstream, subtract the speed of the current from the speed of the boat in still water.
Step 5: Calculate the speed upstream: 10 km/h (boat speed) - 2 km/h (current speed) = 8 km/h.
Step 6: Conclude that the speed of the boat upstream is 8 km/h.

Relative Speed – Understanding how to calculate the effective speed of a boat when considering the influence of a current.
Upstream vs Downstream – Differentiating between the speeds of a boat traveling upstream (against the current) and downstream (with the current).
