A policeman noticed a thief at some distance. The policeman started running to catch the thief and the thief also started running at the same time. The speed of both policeman and the thief was 12 km per hour and 10 km per hour, respectively. It took 30 minutes for the policeman to catch the thief. Find the initial distance (in metres) between them.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 1000.
he policeman started running to catch the thief and the thief also started running at the same time
So,
Relative speed = Speed of policeman - speed of thief
Relative speed = 12 - 10 = 2 km/hr
Now,
Distance = Speed × Time
Distance = 2 × 30/60 = 2/2 = 1 km
Thus,
The initial distance between the policeman and the thief was 1 km or 1000 meters
