Question
A thief is noticed by a policeman from a distance of 600 m.
The thief starts running, and the policeman chases him. The thief and the policeman run at the rate of 15 km/h and 18 km/h, respectively. What is the distance between them after 10 minutes?Solution
ATQ;
Relative speed of policeman w.r.t thief = 18 - 15 = 3 km/h
Initial distance between thief and policeman = 600 m
Total distance diminished between them in 10 min = 3 × (10/60) × 1000 = 500 m
Hence, distance between them after 10 min = 600 - 500 = 100 m
