Michael drives x miles due north at arrives at Point A. He then heads due east for y miles. Finally, he drives z miles in a straight line until he reaches his starting point. If x, y, and z are integers, then how many miles did Michael drive if the shortest leg was 5 miles?
(A) 5 miles
(B) 12 miles
(C) 25 miles
(D) 30 miles
(E) Cannot be determined by the information given.
Kudos for correct solution.

This question is repeated..
My solution again is
Since it is given that it travel north first , then east and finally meets the starting point so it constitutes a right angle triangle
since x,y,z are integers and 5 is the shortest distance.
Thus we know the sides of the right angle triangle and shortest side 5 is given by 5:12:13
SO the total distance traveled by him is 5+12+13=30. Option D
