A hiker goes 3 miles north, 2 miles east, one mile south, 4 miles east and then 2 miles north. After an injury, he sends his coordinates to a helicopter rescue team. If the helicopter starts at the same place as the hiker did, and it flew in a straight path to the hikers ending location, approximately how many miles did the helicopter have to fly? Solve using pythsgorean theorem and diagram

Answer 1

northern direction
= 3 - 1 + 2 = 4
eastern direction
= 2 + 4 = 6

h^2 = 4^2 + 6^2 = 52
the hypotenuse is √52 = appr. 7.2 miles
