Question

________is a ratio comparing two quantities with different kinds of units

Answer 1

Rate

Explanation:

The rate of one quantity with another quantity (usually of different units) is the ratio that compares those two quantities. In other words, a rate is a comparison of two quantities of different units in ratio form. For example;

We know that velocity is the rate at which distance changes with time. This means that velocity is a rate comparing two different quantities which are distance and time which both have different units. Distance has an S.I unit of meters(m) while time has an S.I unit of seconds(s). This can be written as follows;

Velocity = distance : time or
`(distance)/(time)`

Answer 2

Rate

Explanation:

Rate is basically also a ratio. but it is the comparing of two different quantities with different units.

As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.

for example:

When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.

20 meters : 15 seconds

thus the lowest form of this relationship will be:

4 meters : 3 seconds

when i write it in Decimal form it becomes :

Ans : 1.33 meters/second (Distance per unit time)

As this ratio have remaining units thus it is referred to as "RATE".
