Hi,
Let x represent How far from delhi the two trains will meet:
Note train comeing from amristar travels 53&lt;sup&gt;1&lt;/sup&gt;&amp;frasl;&lt;sub&gt;3&lt;/sub&gt;miles before the 4pm train starts from Dehli
 Time = time
 x/60mph = (396 &lt;sup&gt;2&lt;/sup&gt;&amp;frasl;&lt;sub&gt;3&lt;/sub&gt;-x)/80mph 
 ||Multiplying thru by 240 so as all denominators = 1
 4x = 3(396 &lt;sup&gt;2&lt;/sup&gt;&amp;frasl;&lt;sub&gt;3&lt;/sub&gt;  -x) 
      {{{7x = 3(1190/3)}}}
         7x = 1190
       x = 170mi from delhi the two trains will meet
