So rate of change of distance between them (dh/dt) = sqrt[(dx/dt)^2 + (dy/dt)^2)]
My answer is sqrt(39000) while book is 390

ur differentiation is incorrect

Suppose the distance between the planes is h. Then:
h^2 = x^2 + y^2
Try differentiating this with respect to t.

that'd do. I just don't understand why it doesn't match if I try to differentiate h = sqrt(x^2 + y^2)

If h = √(x^2 + y^2), then dh/dt is not √((dx/dt)^2 + (dy/dt)^2).

Thank you...

Sorry, I am not familiar with this classification. I had a bit of calculus in school, then for two years in university.
