Question
How far will 'Arjun' travel by the time he catches up to
'Rohan', given that 'Arjun' starts 150 km behind and moves at 55 km/h while 'Rohan' moves at 35 km/h?Solution
ATQ,
Relative speed of 'Arjun' w.r.t 'Rohan' = 55 - 35 = 20 km/h
Time taken by 'Arjun' to overtake 'Rohan' = (150/20) = 7.5 hours
So, distance covered by 'Arjun' in 7.5 hours = 55 × 7.5 = 412.5 km
