<image>Given that there are three points on the number line, \(A\), \(B\), and \(C\), representing the rational numbers \(-24\), \(-10\), and \(10\) respectively, point \(P\) starts from \(A\) and moves towards the endpoint \(C\) at a speed of 4 units per second. Let the time of movement be \(t\) seconds. 
(1) Express the distance between point \(P\) and \(A\) in terms of \(t\): \(PA =\_\_\_\_\); the number corresponding to point \(P\) is \_\_\_\_;
(2) Point \(Q\) starts from point \(B\) and moves towards the endpoint \(C\) at a speed of 1 unit per second. If \(P\) and \(Q\) start moving simultaneously, find: After how many seconds will the distance between point \(P\) and point \(Q\) be 8 units?
