Proportional
A rate.
That is known as a unit rate.
A rate is a ratio of two quantities: miles per hour, calories per cookie, dollars per person, ... a unit rate just specifies the units (miles, hours) of the two quantities.
I=Prt is a multiplication problem. All you need is the Principle, rate, and time. Then you multiply then together.
Imagine you have 20 objects at a cost of $90. Then the unit rate (the cost of one object) will be found by division. here $90 ÷ 20 = $4.50 (the unit price)
That's a rate, or more commonly, a ratio.
To compare to different units of measurement or a ratio that compares two quantities of different units (Ex: A car goes 100 miles in 1.5 hours, what is the rate)
[Directly] proportional quantities.
Speed is the rate at which an object moves, while velocity is the rate at which an object changes its position. Acceleration, on the other hand, is the rate at which an object changes its velocity. Speed and velocity are scalar quantities, while acceleration is a vector quantity.
The cell division rate slows down and evetually stops.
A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.

A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
