Step-by-step explanation:
Given : Ajay walked 3 km towards North. Then he took left turn and walk 6 km. Finally he took a right turn and walk 5 km
To Find : minimum distance from the starting point to ending point
Solution:
NORTH
WEST EAST
SOUTH
Ajay walked 3 km towards North
NORTH = 3 km
took left turn and walk 6 km
Left turn from North is West
WEST = 6 km
a right turn and walk 5 km
Right turn from West means North
NORTH = 5 km
Total NORTH = 3 + 5 = 8 km
Total WEST = 6 km
NORTH & WEST are perpendicular to each other
Minimum Distance = √8² + 6²
= √64 + 36
= √100
= 10
minimum distance from the starting point to ending point = 10 km
