Respuesta :

Answer:

100 inches Over 1 minute times × 1 foot Over 12 inches

Step-by-step explanation:

Remember that

[tex]1\ ft=12\ in[/tex]

so

[tex]1\ in=1/12\ ft[/tex]

we have

[tex]100\frac{in}{min}[/tex]

Convert to ft/min

To convert in/min to ft/min multiply the given value by the factor 1/12

[tex]100\frac{in}{min}(1/12)\frac{ft}{in}=8.33\ ft/min[/tex]

therefore

100 inches Over 1 minute times × 1 foot Over 12 inches

100 inches Over 1 minute times × 1 foot Over 12 inches
