Answer: To find the distance between Jannick's house and Milos' house, we can use the Pythagorean theorem. We first need to find the total distance travelled by Jannick:
Distance north + Distance east + Distance south =
√(2^2 + 5^2) + 4.5 = √29 + 4.5 ≈ 8.74 miles
Therefore, the distance between Jannick's house and Milos' house is approximately 8.74 miles.
