Question 1108277
.
<pre>
Your "time" equation for the unknown distance d (in miles) is 


{{{d/6}}} + {{{d/16}}} = {{{5/2}}}   hours   (notice {{{5/2}}} = {{{2}}}{{{1/2}}} !)


To solve it, multiply both sides by 48. You will get


8d + 3d = 5*24,

11d = 120  ====>  d = {{{120/11}}} = {{{10}}}{{{10/11}}} miles.


<U>Answer</U>.  The distance under the question is  {{{10}}}{{{10/11}}} miles.
