Question

A shape of a university campus is a square with side length of 10 miles. If you imagine the university on the x-y plane, in the first quadrant with two sides of the square on the positive axes, then the student union is at the origin (at a corner of the square). At noon on a certain day an announcement was made that all students had to walk to the student union. At that time the density function of the students spread over campus was given by:

f(x, y) = (3/20000)*(x^2 + y^2 )       0 < x < 10,  0 < y < 10,

0 otherwise.

If students are only allowed to walk parallel to the axes what is the expected value of the distance walked to the student union by a randomly chosen student on campus? (Assume that students walk in a way that monotonically decreases their distance to the student union. That is, they don’t walk ” backward”.)
