Answer 1

We know that

1 foot = 12 inches

Therefore,

`1\text{ inch = }\frac{1\text{foot}}{12\text{ inches}}\text{ }`

Here, we are told to convert 100 inches per minute to feet per minute.

To convert 100 inches per minute to feet per minute, multiply by 1 foot/12 inches.

Thus, we have:

`\frac{100inches}{1min\text{ute}}\text{ }\ast\text{ }\frac{1\text{foot}}{12\text{inches}}`
