• By 10 AM ravi starts hence by 12 AM with a speed of 4kmph he would have travelled 8kms.Hence the distance between ravi & raja by 12 PM is 12 kms
  By 1 pm ravi travels another 4 kms & raja 1 km, hence now distance is between them is 7 kms by 2pm there distance is 1 km
  suppose they meet after t hrs
  then 4t+3t=1 or,t=1/7*60=8.57min then at 2.8pm they will meet

• Answer is 1.15 PM
  By 10 AM ravi starts hence by 12 AM with a speed of 4kmph he would have travelled 8kms.Hence the distance between ravi & raja by 12 PM is 12 kms
  By 1 pm ravi travels another 4 kms & raja 1 km, hence now distance is between them is 3 kms
  ravi 4km=60mins
  hence 1km=15mins
  when ravi reached 17 kms by 1.15 PM at the time raja would have travelled 3 kms.
  Hence they meet by 1.15PM.
