3 metres from one end to the third mark
Solution:
Total length of wood = 10 metre
Wood is marked into 10 equal length.
[tex]$\text{Length of each marking}=\frac{\text{Total length}}{\text{Number of marking}}[/tex]
[tex]$=\frac{10}{10}[/tex]
= 1 metre
Length of each marking = 1 metre
Number of metres from one end to third mark = 1 + 1 + 1 = 3 metre
The image of the marking is attached below.
Hence 3 metres from one end to the third mark.
