Answer: 180 inches
Step-by-step explanation:
We can use dimensional analysis. Our desired units are inches per yard. Begin by writing down:
[tex]\frac{12in}{1ft}[/tex]
Then use the conversion factor of feet to yard. The units of feet will cancel giving:
[tex]\frac{12in}{1ft} *\frac{3ft}{1yd}=\frac{36in}{1yd}[/tex]
Multiply the top and bottom by 5 to get:
[tex]\frac{36in}{1yd} *\frac{5}{5} =\frac{180in}{5yd}[/tex]
