102 miles to 4 minute = 51 miles to 2 minutes
275/33 x 21 = 175 Therefore, 175 balls would be produced at the same rate in 21 minutes as there would be in 33 minutes.
A fraction is a numerical constant. Being a fraction does not alter that. And, as a constant, its rate of change is precisely zero.
She would run 2.4 miles in 18 minutes.
Unit rate
4/1
An investment's rate of return is expressed as a percentage.
Rate is the amount of something per unit time. Miles per hour and gallons per minute are examples of rates. Ten miles per hour, expressed as a fraction, is 10 mi/hr. Five meters per second: 5 m/s. Example Problem If you run a 26.2-mile marathon in four hours and 15 minutes, then your average rate was 26.2/4.25 = 6.16 mi/hr.
102 miles to 4 minute = 51 miles to 2 minutes
275/33 x 21 = 175 Therefore, 175 balls would be produced at the same rate in 21 minutes as there would be in 33 minutes.
Both would increase
It is the percentage rate of change!

A million minutes...
No it cannot.
Inflation of prices. Population growth, particularly in comparison between different countries. Decline of animal and bird populations. That's three for a start. Anything that has a change expressed as a fraction (over a day, month, year etc).
