Question 1144885
.
<pre>
Let "d" be the distance under the question, in kilometers.


Then you have this time equation


    {{{d/15}}} + 1 + {{{d/30}}} = 7   hopurs.


Simplify


    {{{d/15}}} + {{{d/30}}} = 6.


Multiply both sides by 30


    2d + d = 180

    3d     = 180

     d     = 180/3 = 60.


<U>ANSWER</U>.  60 kilometers.
