Answer 2

Calculation of Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to consider two different segments of the journey: the time spent on the lake and the time spent on the river.

1. Time spent on the lake: The boat traveled for 3 hours on the lake at a speed of 23 kilometers per hour. Therefore, the distance covered on the lake can be calculated as follows:

Distance on the lake = Speed × Time = 23 km/h × 3 hours = 69 kilometers.

2. Time spent on the river: After spending 3 hours on the lake, the boat continued its journey on the river for 4 hours. The speed of the boat on the river is not provided in the question. However, it is mentioned that the boat traveled 3 kilometers per hour faster on the river compared to the lake. Therefore, we can calculate the speed on the river as follows:

Speed on the river = Speed on the lake + 3 km/h = 23 km/h + 3 km/h = 26 km/h.

Using this speed, we can calculate the distance covered on the river:

Distance on the river = Speed × Time = 26 km/h × 4 hours = 104 kilometers.

3. Total distance traveled: To find the total distance traveled by the boat during the 7-hour journey, we add the distances covered on the lake and the river:

Total distance = Distance on the lake + Distance on the river = 69 kilometers + 104 kilometers = 173 kilometers.

Therefore, the boat traveled a total distance of 173 kilometers during the 7-hour journey.

Conclusion

In summary, the boat traveled 69 kilometers on the lake and 104 kilometers on the river, covering a total distance of 173 kilometers during the 7-hour journey.
