116.if a person moves 15km straight and turns 45km right and moves 15km straight then how much distance he needs to walk to reach starting point?

• Take the co-ordinate of the point where he starts as (0,0)
  From the sum we get the co-ordinate of the point after he has walked 15km second time as (45,30)
  Distance = sqrt(45*45 + 30*30)
  = sqrt(2925)
  which is approx 54
