Question 754865
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 / 350 }}} = Sukriti's speed in km/sec
Let {{{ t }}} = Sukriti's time to run {{{ 5 }}} km
{{{ 5 = ( 1/350 )*t }}}
{{{ t = 1750 }}} sec
------------------
Let {{{ d }}} = Saloni's distance covered in this time
{{{ d = ( 1/364 )*1750 }}}
{{{ d = 4.8077 }}} km
-------------------
The difference is 
{{{ 5 - 4.8077 = .192 }}} km
{{{ .192*1000 = 192 }}} m
The closest answer is (C) 200 m
