Consider the instance when Suresh just starts from the office.
Distance that Pradeep has already covered in that time = 50*1.5 = 75 km
Now, by concept of relative velocity, time taken by Suresh to just overtake Pradeep = 75/(60-50) = 7.5 hours
Hence, the point of overtaking on the route is = 60*7.5 = 450 km from the office
Subodh also overtakes Pradeep at the same point. Pradeep covers this 450 km distance in 9 hours.
Subodh can cover this 450 km in 6 hours.
Hence, Subodh can leave 9 - 6 = 3 hours after Pradeep does.
