Disclaimer: Exchange rates vary almost on a constant basis, so it is best to always have an up-to-date chart from an online source. For the purposes of this problem, we don't have to worry about the rates changing.
------------------
25 U.S Dollars = 20 Euros
25/20 U.S. Dollars = 20/20 Euros
1.25 U.S. Dollars = 1 Euro
<h3>The exchange rate is 1.25 U.S. Dollars per Euro</h3>
Saying "per Euro" is the same as saying "per 1 Euro". I divided both sides of the second equation by 20 so that I could turn the "20 Euros" into "1 Euro".
We have that the stream of water is coming out in small quantities; at most liters at a time since the stream has a width of around 10cm at most times. Hence, cubic meters per second is too large a unit to measure the small quantity of water going through the shower.
We have that we can calculate the rate if we know the surface area of the flow and the speed of the water. If one multiplies those 2 together, one gets the rate because the speed of water is pretty much how much a front of water is moving per second; if you multiply it by its surface area, you get how much a volume of water is moving.
Answer:
No, it is unreasonable.
Step-by-step explanation:
5/5/6+1/3/4=35/6+7/4
=70/12+21/12
=91/12
=7 7/12
