Downstream DATA:
distance = 12 miles
time = 2 hours
rate = 12/2 = 6 mph
----------------
Upstream DATA:
distance = 12 miles
time = 4 hrs
rate = 12/4 = 3 mph
----
Equations:
Downstream: b + c = 6
Upstream::: b - c = 3
------
Add to get:
2b = 9
b = 4.5 mph (speed of the boat in still water.)
-----
Solve for "c":
b + c = 6
4.5 + c = 6
c = 1.5 mph (speed of the current)
The answer is 1.5 mph

Step-by-step explanation:
Answer:
y = 5
General Formulas and Concepts:
<u>Alg I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
Step-by-step explanation:
<u>Step 1: Define variables</u>
Point (-2, 5)
Slope <em>m</em> = 0
<u>Step 2: Write function</u>
y - 5 = 0(x + 2)
y - 5 = 0
y = 5
<u>Step 3: Identify</u>
y = 5 is a horizontal line.
