Total distance traveled from the starting point = 487 mm (or) 0.487 m

Solution:Given data:

Length of each block = 135 mm

Distance traveled towards North = three blocks

= 135 × 3

= 405

Distance traveled towards North = 405 mmDistance traveled towards West = two blocks

= 135 × 2

= 270

Distance traveled towards West = 270 mmTotal distance traveled

[tex]=\sqrt{\text{Distance traveled in North}^2+\text{Distance traveled in West}^2}[/tex]

[tex]=\sqrt{405^2+270^2}[/tex]

[tex]=\sqrt{236925}[/tex]

[tex]=135\sqrt{13}[/tex]

= 487 mm (approximately)

Total distance traveled from the starting point = 487 mmLet us convert mm to m.

1 m = 1000 mm487 mm = 487 ÷ 1000 =

0.487 mTotal distance traveled from the starting point = 0.487 m
