Rishabh stops after going 10 Km towards west from his office. Then he goes 8 Km turning to his left. After this he goes 4 Km turning to his left. How far is he from the fixed point?

Solution

Start from office (fixed point).
Move 10 km west.

Left from west = south → move 8 km south.

Left from south = east → move 4 km east.

Net west movement = 10 − 4 = 6 km (west).
Net south movement = 8 km (south).

Distance from office = √(62 + 82)
= √(36 + 64) = √100 = 10 km

Answer: 10 km
