A Boat Moves Upstream at the Rate of 1 km in 20 Minutes
This problem involves understanding the concepts of speed, distance, and time in the context of moving water. Let's break down the problem and find out what we can determine about the boat's movement.
Understanding the Information
- Upstream: This means the boat is moving against the current of the river. The current will slow the boat down.
- 1 km in 20 minutes: This tells us the boat's effective speed while moving upstream.
Calculating the Boat's Speed
To find the boat's speed, we need to convert the time into hours:
- 20 minutes is equal to 20/60 = 1/3 of an hour
Now, we can calculate the boat's speed:
- Speed = Distance / Time
- Speed = 1 km / (1/3 hour) = 3 km/hour
Therefore, the boat's effective speed upstream is 3 km/hour.
Important Note:
This calculation only tells us the boat's speed relative to the riverbank. To determine the boat's actual speed (without the influence of the current), we would need additional information about the speed of the river current.
