Ram walks 10 m towards the East, then turns to the North and walks 15 m, then turns to the West and walks 10 m, and then turns to the South and walks 15 m. How far is Ram from his starting point?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 0 m
Keep a running total of the distance east (or west) and north (or south) of the start; walking the same distance in opposite directions cancels out.
10 m East: 10 m east of the start
15 m North: 10 m east, 15 m north
10 m West: \(10-10=0\) m east, 15 m north
15 m South: \(15-15=0\) m north
Ram is back at his starting point, 0 m from it.
