From the question, we know that the solutions of the system
is (14,6), which means the speed of the the boat in calm water,
, is 14
, and the speed of the current,
, is 6
. To summarize:
and
We also know that w<span>hen the boat travels downstream, the current increases the speed of the boat; therefore to find the speed of the boat traveling downstream, we just need to add the speed of the boat and the speed of the current:
</span>
<span>
Similarly, to find the the speed of the boat traveling upstream, we just need to subtract the speed of the current from the speed of the boat:
</span>
<span>
We can conclude that the correct answer is </span><span>
C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.</span>
Answer:
<h3>.A -d = nz</h3><h3>n = (A - d)/z</h3><h3> Hope that will help you</h3>
Answer:
n=-25 and SU=100
Step-by-step explanation:
<u><em>Solve for n</em></u>
4n-18=32-6n
-2n=50
n=-25
<u><em>Solve for segment SU</em></u>
4(-25)-18+32-6(-25)=SU
-100-18+32+150=SU
-82+182=SU
100=SU
<span>19d - 20 is the answer because you need to simplify.</span>
Hi so let's try to simplify 1/4... it's already simplified so if you were to try to simplify 2/8 you would divide 2 by 2 and 8 by 2 to get 1/4. But 1/4 isn't = to 1/2. So let's simplify 2/4, first, you would divide 2 by 2 and 4 by 2 to get 1/2. C is the answer!=D I hope this helps.
