Correct Answer - Option 1 : 175 m
Given:
A thief is noticed by a policewoman at a distance of 300 m. The policewoman ran after thief to chase him.
The thief and the policewoman ran at the speed of 8.5 km/hr and 10 km/hr respectively.
Concepts used:
Relative speed = Speed of policewoman – the speed of thief
Distance = Relative speed × time
Calculation:
Relative speed = 10 km/hr – 8.5 km/hr = 1.5 km/hr
Distance = Relative speed × time
Distance between thief and policewoman after 5 minutes = 1.5 × (50/3) × 5 = 125 m
A thief is noticed by a policewoman at a distance of 300 m.
Total distance = 300 m
Remaining distance = Total distance – Distance between thief and policewoman after 5 minutes
⇒ 300 m – 125 m = 175 m
∴ Distance remaining to be covered between them after 5 minutes is 175 m.
