Question

A man goes 15m due west and then 8m due north how far is he from the starting point

Answer 1

A man goes due west = 15 m

                   due North  = 8 m

distance from the initial point  = sq. root of 15^2 +  8^2

                                                 = sq. root of 225 + 64

                                                 = sq. root of 289

                                                = 17 m
