Theres a fun trick when it comes to saying something 'per' something;
as you can look at the word per as a fancy word for divide.
So if I have Xylophones per Megaphone then I'm basically saying:
Xylophones divided by megaphones
So in this case its 10 feet per 2 1/2 minutes and we'd understand it as 10/2.5
Lets show this
10 ft per 2 1/2 minutes = 10/2.5 ft/min = 4 ft/min
Hope this helps :)

Answer:
x - 2
Step-by-step explanation:
2x - 1 + 4x - 11
First, you want to combine like terms.
We can see that the one and eleven can go together, so add them together.
2x + 4x - 12
The reason that we made one, and eleven, negative twelve, is because they are both being subtracted from the numbers before that.
6x - 12
We added the 2x, and the 4x together to make 6x.
Another way to write this would be x - 2, because you can simplify it by dividing it by 6.
