Question

Which expression converts 100 inches per minute to feet per minute?

Answer 1

Answer:

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

Step-by-step explanation:

Remember that

$1\ ft=12\ in$

so

$1\ in=1/12\ ft$

we have

$100\frac{in}{min}$

Convert to ft/min

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

$100\frac{in}{min}(1/12)\frac{ft}{in}=8.33\ ft/min$

therefore

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

Answer 2

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