'A' and 'B' start from the same place and walk in opposite directions, each traveling 20 m. 'A' then turns right and walks 15 m. 'B' turns left and walks 15 m. How far are they now from each other?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 40 m
Each turn is taken from the direction the person is facing at that moment. Take A walking North and B walking South (any pair of opposite directions gives the same answer):
A faces North; a right turn is East (15 m)
B faces South; a left turn is also East (15 m)
Both move 15 m East, so the 15 m walks do not change the gap between them: A is 20 m North and B 20 m South of the same line, \(20+20=40\) m apart.
