Answers
Given : sam walks 20 meters (m) towards south.
He turns to his left and walks 10m, and
then, turns left again and walks another 10m.
Once again, turning left, he walks 20m more.
To Find : How far, and in which direction is Sam with respect to his original position?
Solution:
NORTH
WEST EAST
SOUTH
South = 20 m
Left from south means East
East = 10 m
Left from east means North
North = 10 m
Left from North means West
West = 20 m
South = 20 and North = 10 => South = 10 m
East = 10 and West = 20 => West = 10 m
South = 10 West = 10
Distance from original = √(10² + 10²) = 10√2 m
and direction is Southwest
Sam is in south west direction from original at distance of 10√2 m
