Problem Analysis

To solve this problem, we need to find the speed of the boat in meters per minute. We are given that the boat travels 100 meters in 15 seconds, and we need to calculate the distance it travels in 1 minute and 8 minutes.

Solution

1. Speed Calculation: - First, let's calculate the speed of the boat in meters per second. - Speed = Distance / Time - Speed = 100 meters / 15 seconds - Speed = 6.67 meters per second

2. Distance Traveled in 1 Minute: - Now, let's calculate the distance the boat travels in 1 minute. - Distance = Speed * Time - Distance = 6.67 meters per second * 60 seconds (1 minute) - Distance = 400 meters

3. Distance Traveled in 8 Minutes: - Next, let's calculate the distance the boat travels in 8 minutes. - Distance = Speed * Time - Distance = 6.67 meters per second * 480 seconds (8 minutes) - Distance = 3200 meters

Results

- The boat travels 400 meters in 1 minute. - The boat travels 3200 meters in 8 minutes.
