Question 1164046
.


            Even if you are a beginner student,  there are at least two different and simple ways to solve the problem.



<U>1. &nbsp;&nbsp;Using the rate</U>


<pre>
    Then the problem is solved in two steps.

    First, you find the rate; next, you find the required time.


    The rate is the distance divided by the time.   In your case, it is

        rate = {{{189/7}}} = 27 miles per hour.


    Then the required time is  the distance divided by the rate:

        the required time = {{{216/27}}} = 8 hours.    <U>ANSWER</U>
</pre>


<U>2.  &nbsp;&nbsp;Using proportions &nbsp;(if you are familiar with it)</U>.


<pre>
       {{{189/7}}} = {{{216/x}}},

       where x is the unknown time.

       From the proportion,  x = {{{(216*7)/189}}} = 8 hours.


       You get the same answer.
</pre>

You may choose which way suits better for you.
