Question 1145611
.


            In my solution, I will use decimals instead of fractions.



<pre>
{{{4/5}}} = 0.8;    {{{2}}}{{{3/5}}} = 2.6.


Let x be the unknown length of the entire race.


Then the equation is


    0.8*x = 2.6.

The solution/(the answer) is


    t = {{{2.6/0.8}}} = 3.25 kilometers = {{{3}}}{{{1/4}}} kilometers.
