A grasshopper starts at the origin in the coordinate plane and makes a sequence of hops. Each hop has length
5

, and after each hop the grasshopper is at a point whose coordinates are both integers; thus, there are
12
12
12
possible locations for the grasshopper after the first hop. What is the smallest number of hops needed for the grasshopper to reach the point
