A child went 90 feet to the west to look for his father, then he turned right and went 20 feet . After this, he turned right and walked 30 feet to reach his uncle's house. His father was NOT there. From there he went 100 feet to his south and met his father. How far did he meet his father from the starting point?

Solution & Step-by-step Explanation

Let the starting point be (0, 0) . 1. Moves 90 feet West: (- 90, 0) 2. Turns right (North) and goes 20 feet : (- 90, 20) 3. Turns right (East) and walks 30 feet to uncle's house: (- 90 + 30, 20) = (- 60, 20) 4. From here, he goes 100 feet South: (- 60, 20 - 100) = (- 60, - 80) Now, we need to find the distance between the starting point (0, 0) and the final point (- 60, - 80) : Distance = (- 60)^{2} + (- 80)^{2} = 3600 + 6400 = 10000 = 100 feet
