Question 423839


first:

the primary element to learn is the main formula... 

This equation is:

{{{Distance = Rate* 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 * Time}}}

{{{Distance = 60mph * 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 * 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/Rate}}}

{{{Time = 120miles/60mph}}}

{{{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 * 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/Time}}}

{{{Rate = 120 miles/2 h}}}

{{{Rate = 60mph}}}
