```							VP = 90 km/h = 25 m/s.VC = 72 km/h = 20 m/s. Time taken by the culprit to reach B from A= 10sDistance converted by culprit  = v x t = 20 x 10 = 200 m. At time t = 10 sec the police jeep is 200 m behind theculprit.Time = s/v = 200 / 5 = 40 s. (Relative velocity is considered).In 40 s the police jeep will move from A to a distance S, whereS = v x t = 25 x 40 = 1000 m = 1.0 km away.Thus the jeep will catch up with the bike, 1 km far from the turning.
