1. If arthur walks 3 km north, and then turns east and walks 4 km. The  distance traveled  is 7km and his displacement is 5km.

   Distance travelled and displacement

   Distance traveled:

   Distance traveled = Km north + East Km

   Distance traveled  = 3 km + 4 km

   Distance traveled  = 7 km

   Displacement

   Using  Pythagoras theorem to determine  or find the displacement

   B² = A ²+AB²

   B² = 3 ² +4 ²

   B = 9+16

   B = √ 25

   B = 5 km

   Therefore the 7km is the distance and 5km is the displacement.
