3 metres from one end to the third mark
Solution:
Total length of wood = 10 metre
Wood is marked into 10 equal length.
![$\text{Length of each marking}=\frac{\text{Total length}}{\text{Number of marking}}](https://img.qammunity.org/2021/formulas/mathematics/middle-school/312wcj9c17txmnks9q8vqyf9d3irgq0anc.png)
![$=(10)/(10)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8oxov4kotgeku28egoef8rv1y8rt2boxoo.png)
= 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.
