first:
the primary element to learn is the main formula...
This equation is:

if we are given the rate at which someone is traveling and the time it takes to travel, we can then calculate the total distance traveled
second:
Consider the following example:
A car travels at 60mph and drives for 2 hours. We need to calculate the distance the car traveled.




third:

Now, lets say that we want to know how long it will take us to travel miles at a rate of .
We know that , but we want to calculate . We need to rearrange the formula. We need to have on one side of the equation by itself, so we must divide both sides of the equation by the Rate. The new formula will look like this.




fourth:
We have learned how to calculate both distance and time using this formula, so let's look at how to figure the Rate. We will use the same example. A car has driven for 2 hours and traveled 120 miles. What rate of speed was the car traveling?
We know that , but we want to calculate . Again, we need to rearrange the formula. We now want to have the on one side of the equation by itself, so we must divide both sides of the equation by the Time. The new formula will look like this.
