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:
-2.125
Step-by-step explanation:
Answer:
473 milliliters.
Step-by-step explanation:
We have been given that there are 946 milliliters in a quart. There are 2 pints in a quart.
To find the number of milliliters in a pint we will divide 946 by 2.
Therefore, there are 473 milliliters in one pint.
