ATQ, Speed of Karan = (2,400/40) = 60 km/h Speed of Mohit = (2,400/32) = 75 km/h Distance covered by Karan in 2 hours (from 7:00 AM to 9:00 AM) = 60 X 2 = 120 km Relative speed of Mohit w.r.t. that of Karan = 75 - 60 = 15 km/h Time taken by them to meet each other = (120/15) = 8 hours So, required time = 9:00 AM + 8 hours = 5:00 PM Required distance = 75 X 8 = 600 km
