sukirti and saloni are athletes. Sukirti covers a distance of 1 km in 5 minutes and 50 seconds, while saloni covers the same distance in 6 minutes and 4 seconds. If bout them start together and run at uniform speed, by what approximate distance will sukirti win a 5 km mini marathon?

• sukirti and saloni are athletes. Sukirti covers a distance of 1 km in 5 minutes and 50 seconds, while saloni covers the same distance in 6 minutes and 4 seconds. If bout them start together and run at uniform speed, Sukriti will cover 5 kms in 175/6 mins and during that time ( 175/6 mins), Saloni will cover 125/26 kms.
  sukirti will win a 5 km mini marathon by 5-125/26 = 5/26 kms

• 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
