Question 1174120
.


Another possible way to solve the problem is to use the "time" equation.



<pre>
Let d be the distance under the question.


Then you have this "time" equation


    {{{d/66}}} = {{{(d-42)/42}}}.


To solve it, cross-multiply, then simplify


    42d = 66*(d-42)

    42d = 66d - 66*42

    66*42 = 66d - 42d

    66*42 = 14d

      d   = {{{(66*42)/14}}} = 66*3 = 198 miles.    <U>ANSWER</U>

If you go this way, making equation is easy;

its solving is easy, too.


Another advantage is that you go straight way to your unknown quantity.



Solved.
