Question 1188476
.
Mr. Thimas drove his old truck to the city at a rate of 40mi/hr and drove back home 
on the interstate at 60mi/hr. The total trip took 6 hours. 
How far is Mr. Thomas's home from the city
~~~~~~~~~~~~~~


<pre>
Let d be one way distance (which is the unknown value under the problem's question).


Write the total time equation


    {{{d/40}}} + {{{d/60}}} = 6  hours.


To solve it, multiply both sides by 120.  You will get


    3d + 2d = 6*120

      5d    = 720

       d    = 720/5 = 144 miles.


<U>ANSWER</U>.  The distance is 144 miles.

Solved (and corrected).
