Question

Where might you see rates in the real world?

Answer 1

A few more examples you may see in the physical sciences and engineering:

 

velocity = rate of change of position with respect to time

acceleration = rate of change of velocity with respect to time

current = rate of change of charge with respect to time

mechanical power = rate of change of mechanical work with respect to time

electromotive force = -(rate of change of magnetic flux with respect to time)

 

There are many other rates.  There are rates in the social sciences too.

 

Answer 2

Finance, gas mileage, heart conditions, hourly wage, etc.

 

This is a good question you ask.  This will help relate math to the real world and understand math better.  Math is like history and science, in which it must be taught with real world relevance.
