You can put this solution on YOUR website! You sail 6mph with the wind. You sail 4mph against the wind. What is your actual speed, speed of the wind, and equation for solving.
-----
Equations:
b + w = 6 mph
b - w = 4 mph
----
Add and solve for "b"
2b = 10 mph
b = 5 mph (speed of the boat when there is no wind)
---
Solve for "w":
b + w = 6 mph
5 + w = 6
w = 1 mph (speed of the wind)
