Answer:
The factor which is used to convert feet per minute into miles per minute is: 1 ft per minute=0.000189 miles per minute. (since, 1 ft.= 0.000189 miles)
Explanation:
A conversion factor is a factor which is used to convert one unit to another by multiplication or division by a specified number.
We know that:
1 miles= 5280 ft.
This means that:
1 ft.=1/5280 miles
i.e. 1 ft.= 0.000189 miles.
Hence, 1 ft per minute=0.000189 miles per minute.
