There was two trains from calcutta to kanyakumari one train is fast service travels with a speed 75km per hour another travels with a speed of 44km per hour the time taken to reach from calcutta to kanyakumari is 4hours less than the first train...find the distance b/w calcatta to kanyakumari

• let distance b/w calcutta to kanyakumari is = x km
  then eqn is
  x/44 - x/75 = 4
  => x*(75-44)=4*75*44
  => x = 425.8 km

• let distance b/w calcutta to kanyakumari is = x km
  then eqn is
  x/55 - x/75 = 4
  => x*(75-55)=4*75*55
  => x = 825km

• 75(t-4)=44t=d
  =>t=300/31
  d=44*300/31=425.8 kms

• 4=d/55-d/55
  
  solving this d= 825km
• 10 years agoHelpfull: Yes(3) No(5)
• (d/44)-(d/75)=4
  => d=425.80

• ans is 825 km.
  if the first train takes x hours then the second train will take x-4 hours.on equating the distance b/w 2 stations we get, 75x=55(x-4) hence x= 11 hrs. hence dist b/w stations is 75*11=825kms.
