Directions: Read the following information and give answer.Kamran walks 10km towards North. From there he walks 6km towards South. Then, he walks 3km towards East. How far and in which direction is he with reference to his starting point?
Correct answer: D. 5 km North-East
- A. 5 km West
- B. 7 km West
- C. 7 km East
- D. 5 km North-East
Explanation
Kamran first moves 10 km North and then 6 km South, resulting in a net movement of 4 km North. He subsequently moves 3 km East. To determine the overall distance from the starting point, use the Pythagorean theorem:a^2 + b^2 = c^2, where a = 4 km and b = 3 km:4^2 + 3^2 = c^216 + 9 = c^225 = c^2c = √25 = 5 kmThe direction is informed by the combined North and East movements, placing Kamran in a North-East direction.Thus, Kamran is 5 km North-East of his starting point. Options A, B, and C are incorrect because they either miscalculate the distance or misinterpret the direction.
