(1)
+d+=+r%2At+
+d+=+30%2A5+
+d+=+150+ km
-----------------
(2)
+d+=+r%2At+
+96+=+32%2At+
+t+=+3+ hrs
----------------
(3)
Tarun has +150+-+96+=+54+ km
left to the journey
The time for Tarun to ride this last part is
+t+=+d%2Fr+
+t+=+54%2F36+
+t+=+1.5+ hrs
----------------
Tarun's total time is+3+%2B+1.5+=+4.5+ hrs
Shakeel's total time is +5+ hrs
---------------------------------
Tarun finishes +5+-+4.5+=+.5+ hrs before
Shakeel does
--------------------
To find the distance between them as Tarun
crosses finish line, find distance Shakeel has
gone in the same time, +4.5+ hrs
+d%5B1%5D+=+30%2A4.5+
+d%5B1%5D+=+135+ km
-------------------
+150+-+135+=+15+
the distance between them as Tarun
crosses finish line is 15 km
