On a number line, let P represent the largest integer value that is less than the square root of 407. Let point Q represent the largest integer value that is less than the square root of 68. What is the difference between P and Q?

%0D%0A20=sqrt%28400%29%3Csqrt%28407%29%0D%0A

and

%0D%0A8=sqrt%2864%29%3Csqrt%2868%29%0D%0A

so the difference between P and Q is 20-8=12
