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
Answer:
-7/8
Step-by-step explanation:
y = 1/8 -1
y = 1/2^3 -1
y = 1 - (2^3)/2^3
y = 1-8/2^3
y = 7/2^3
y = -7/8

Answer:
180
Step-by-step explanation:
add 1% to 31.50 to get 31.815
then take the total 5276.70 and divide by 31.815
<span>3x+2y+4+9y=
Combine like terms:
2y+9y=11y
I believe the answer is 3x+11y+4
(That is unless you know the numbers that y & x equals)</span>
