25 words per minute means 25x
We want ti find how much would it take to read 225 words
So we will have this equation
25x = 225
Solve for x

5 hours
OpenStudy (will.h):
No
OpenStudy (kalebj):
ah... so its 25x = 225 right
OpenStudy (will.h):
25x = 225
To find x (time in minutes) divide both sides by 25
25x/25 = 225/25
X = 9 minutes.

Logically if he reads 25 words in one minute that means 50 words in 2 minutes. So 225 words would take 5 hrs? Absolutely not
