Question 1087169
.
<pre>
{{{D/75}}} = {{{D/105}}} + {{{2}}},    (the "time" equation, where D is the distance)


105*D = 75*D + 2*75*105,


30*D = 2*75*105,


D = {{{(2*75*105)/30}}} = {{{(150*105)/30}}} = 5*105 = 525 miles.


<U>Answer</U>.  The faster train will catch the slower train in 525 miles from the station.
