Questions & Step-by-Step Solutions

A person walks 2 km north, then 2 km east, and then 2 km south. How far is he from the starting point?
  • Step 1: Start at the starting point (let's call it point A).
  • Step 2: Walk 2 km north to reach point B.
  • Step 3: From point B, walk 2 km east to reach point C.
  • Step 4: From point C, walk 2 km south to reach point D.
  • Step 5: Now, point D is directly south of point B, but still 2 km east of point A.
  • Step 6: Therefore, the distance from point A (starting point) to point D is 2 km east.
