Question 423839: How to calculate distance problems

first:
the primary element to learn is the main formula...
This equation is:
Distance+=+Rate%2A+Time
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.
Distance+=+Rate+%2A+Time
Distance+=+60mph+%2A+2+h
Distance+=+120+miles

third:

Now, lets say that we want to know how long it will take us to travel 120+miles at a rate of 60mph.
We know that Distance+=+Rate+%2A+Time, but we want to calculate Time. We need to rearrange the formula. We need to have Time 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.
Time+=+Distance%2FRate
Time+=+120miles%2F60mph
Time+=+2+h

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 Distance+=+Rate+%2A+Time, but we want to calculate Rate. Again, we need to rearrange the formula. We now want to have the Rate 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.
Rate+=+Distance%2FTime
Rate+=+120+miles%2F2+h
Rate+=+60mph
