Convert all times to seconds
Sukriti can cover the same distance in less time, so
Sukriti is the faster runner and finishes the race first.
-----------------
+1+%2F+350+ = Sukriti's speed in km/sec
Let +t+ = Sukriti's time to run +5+ km
+5+=+%28+1%2F350+%29%2At+
+t+=+1750+ sec

------------------
Let +d+ = Saloni's distance covered in this time
+d+=+%28+1%2F364+%29%2A1750+
+d+=+4.8077+ km
-------------------
The difference is
+5+-+4.8077+=+.192+ km
+.192%2A1000+=+192+ m
The closest answer is 200 m
