On a number line, let poin P represent the largest integer value that is greater than √201. Let point Q represent the largest integer value that is less than -√20. What is the distance between P and Q?

 I think that you meant to write " the smallest integer value that is greater than √201 "

 

 P =  ceiling (√201)  ≈ ceiling (14.177)  = 15

 

 Q  = floor ( - √20 )  =   floor ( -4.472 )  = -5

 

Distance between P and Q  =  P - Q  =   15 -  (-5)   =  20 units
