Answer:
The jeep will catch up with the bike, 1km far from the turning.
Explanation:
VP = 90 km/h = 25 m/s.
VC = 72 km/h = 20 m/s.
In 10 sec culprit reaches at point B from A.
Distance converted by culprit S=vt=20×10=200m.
At time t = 10 sec the police jeep is 200 m behind the culprit Time
v s = 200 /5
=40s.
(Relative velocity is considered).
In 40 s the police jeep will move from A to a distance S, where S=vt=25×40=1000m=1.0km away.
∴ The jeep will catch up with the bike, 1km far from the turning.
