Answer 2

The question you asked is a math problem that involves finding the speed and distance of two boats moving in opposite directions on a lake. I found some web search results that might help you solve it. Here is a summary of the information I found:

- Let x be the speed of the second boat in km/h. - The distance between the boats after 3 hours is 87 km, so we can write an equation: 3(14 + x) = 87 - Solving for x, we get x = 15, so the speed of the second boat is 15 km/h . - The distance between the boats after 4 hours is 4(14 + 15) = 116 km. - The distance between the boats after 5 hours is 5(14 + 15) = 145 km.

I hope this helps you understand the problem better. If you need more details, you can check out the web search results I found for you. Have a nice day!
