The thief has a 30-minute head start, which is equal to 0.5 hours.
In that time, the thief covers a distance of 60 km/h * 0.5 h = 30 km.
The police are chasing at 80 km/h, while the thief is driving at 60 km/h.
The relative speed between them is 80 km/h - 60 km/h = 20 km/h. This is the speed at which the police are closing the gap.
The police need to close the 30 km gap.
Time = Distance / Speed = 30 km / 20 km/h = 1.5 hours.
Distance = Speed * Time = 80 km/h * 1.5 h = 120 km.
