<u>Answer: </u>
Distance traveled = 70 meters
Displacement = 36.06 meters
<u>Explanation: </u>
Let north be positive Y and east be positive X
10 meters north, displacement = 10 j meters
20 meters west, displacement = -20 i meters
40 meters south, displacement = -40 j meters
Total displacement = (10 j - 20 i – 40 j) meters = (- 20 i - 30 j) meters
Magnitude of displacement =
Distance traveled = 10+20+40 = 70 meters
