Question: If a boat\'s speed in still water is 10 km/h and it takes 1 hour to travel downstream, how far can it go?

Options:

Correct Answer: 20 km

Solution:

Distance = Speed x Time = (10 + Speed of stream) x 1. Assuming stream speed is 0, distance = 10 km.

If a boat's speed in still water is 10 km/h and it takes 1 hour to travel downstream, how far can it go?

If a boat's speed in still water is 10 km/h and it takes 1 hour to travel downstream, how far can it go?

Step 1: Understand that the boat's speed in still water is 10 km/h.
Step 2: Know that the boat travels downstream for 1 hour.
Step 3: Remember that downstream means the boat is moving with the current of the stream.
Step 4: Assume the speed of the stream is 0 km/h for this problem.
Step 5: Calculate the effective speed of the boat downstream: 10 km/h (boat speed) + 0 km/h (stream speed) = 10 km/h.
Step 6: Use the formula for distance: Distance = Speed x Time.
Step 7: Plug in the values: Distance = 10 km/h x 1 hour.
Step 8: Calculate the distance: Distance = 10 km.

Distance Calculation – Understanding the formula for distance, which is Distance = Speed x Time.
Downstream vs. Still Water Speed – Recognizing the difference between a boat's speed in still water and its effective speed when traveling downstream.
