Question: A boat can travel at 30 km/h in still water. If it goes upstream against a current of 6 km/h, what is its speed relative to the bank?

Options:

Correct Answer: 24 km/h

Solution:

Upstream speed = Speed in still water - Speed of current = 30 km/h - 6 km/h = 24 km/h.

A boat can travel at 30 km/h in still water. If it goes upstream against a current of 6 km/h, what is its speed relative to the bank?

A boat can travel at 30 km/h in still water. If it goes upstream against a current of 6 km/h, what is its speed relative to the bank?

Step 1: Understand that the boat's speed in still water is 30 km/h.
Step 2: Know that the current of the river is 6 km/h.
Step 3: When the boat goes upstream, it moves against the current.
Step 4: To find the speed of the boat relative to the bank, subtract the speed of the current from the speed of the boat in still water.
Step 5: Calculate the upstream speed: 30 km/h (boat speed) - 6 km/h (current speed) = 24 km/h.
Step 6: The speed of the boat relative to the bank when going upstream is 24 km/h.

Relative Speed – Understanding how to calculate the speed of a boat relative to a stationary point (the bank) when considering the effect of a current.
Upstream and Downstream Motion – Differentiating between the speeds of a boat when moving upstream (against the current) and downstream (with the current).
