• 15 minute.....sunil take 30(going to school+return) min less.....so children walked 30/2=15 min

• @Ritabrata time taken for forward and backward journey has to be more than 30 at any cost.

• 45 min. Because if they reach home 30 min earlier then they must have met at a point which is at 15 min driving from the school. So the time would have been 4:45. So they walked for 45 min. :)

• suppose sunil uses to leave for the school at 3 pm and returns home at 7pm . On that sunday he returned home 6:30 pm as per as the question is concerned . He is supposed to maintain a certain velocity . so he happened to meet the child at 4:30 anyway on sunday . This means that the child had to walk 30 mins.

• together they save 30 min
  
  in one trip-15min
  instead of 5pm---4:45pm
  
  school got over 4pm so 4pm--4:45pm it will take 45min
  so 45min answer
