ATQ, Speed of Vikram = (2,100/42) = 50 km/h Speed of Sameer = (2,100/35) = 60 km/h Distance covered by Vikram in 2 hours (from 11:00 AM to 1:00 PM) = 50 X 2 = 100 km Relative speed of Sameer w.r.t. that of Vikram = 60 - 50 = 10 km/h Time taken by them to meet each other = (100/10) = 10 hours So, required time = 1:00 PM + 10 hours = 11:00 PM Required distance = 60 X 10 = 600 km
