Question is attached.Please help me solve this step by step. I have a test coming up.

Solution
Let us first convert feet to inches
1 foot = 12 inches
[tex]\begin{gathered} 1ft=12inch \\ 8ft=x\text{ }inch \\ cross\text{ }multiply \\ x\times1=12\times8 \\ x=96\text{ }inches \end{gathered}[/tex]Distance = 8ft + 11 inches
but 8 ft = 96 inches
Distance = 96 inches + 11 inches
Distance = 107 inches
