input: Write a function to determine the number of jumps of a specified length needed to reach a coordinate (d, 0) from the origin on a 2D plane.
  assert min_Jumps(3,4,11)==3.5
  assert min_Jumps(3,4,0)==0
  assert min_Jumps(11,14,11)==1
output: def min_Jumps(x, y, d):
      distance = (x**2 + y**2) ** 0.5
      return d / distance if distance != 0 else 0
