Question 607250
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)
