Dear student,
Please find the solution to your problem.
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(B → A), S = vt = 20 × 10 = 200 m.
At time t = 10 sec the police jeep is 200 m behind the culprit
Relative speed of jeep w.r.t culprit = 25 – 20 = 5 m/s
Time in which the gap is covered by the police = s/v = 200 / 5 = 40 s.
In 40 s the police jeep will move from A to a distance S, where
S = vt = 25 × 40 = 1000 m = 1.0 km away.
∴ The jeep will catch up with the bike 1 km far from the turning.
Thanks and regards,
Kushagra
