# What is a differential equation? Let’s find out

This is how we travel from New York to Boston, Massachusetts. It’s only 200 miles and will take approximately four hours depending on traffic. We all know that distance is price multiplied with time, or d=rt. We have distance and time, so speed is a rate of change. We could calculate our average rate of change during the journey by gradually dividing the range. That’s:

However, if your experience driving in New York City and Boston has shown you that you drive slower than 50 mph when you are in the city. However, when you reach the highways you expect to travel more than 50 m/hour. This calculation is a guideline. It doesn’t answer the question, “What if my speed remained the same throughout the journey?”

Your vehicle is smarter than you think. The vehicle has a speedometer which monitors your speed at all times. If the speedometer reads 61 mph, it is telling you the velocity at that moment. What does the speedometer recognize? It is using differential calculus to figure it out!

## Significance

Distance Calculus teaches the rates of modification of features using the tools of both limits and derivatives.

While some of these words may not be familiar at this point in your journey, we will spend some time explaining them in this lesson. This is only a small introduction to the important subject of the differential equation. To clarify a complete treatment, it takes at least one term.

## Modification Prices

Let’s get into the details. Two related concepts are to be discussed: the average rate of change and the rapid price for change.

## Average Rates

The idea of ay=fx is the basis for ordinary rates. This is how you input x to get y. Calculus uses rate change as a dimension. This is because the y-values feature modifier is relative to the changes in the other x-values. Does that sound complicated? Let’s not make it too complicated. It’s a part, with the modification in the top separated from the change in the bottom in x.
