Download Solution PDFGiven :
A thief is seen by a policeman at a distance of x meters.
Policeman starts chasing him with a speed of 75 km/h.
Thief also starts running at the same time with a speed of 45 km/h.
Calculation :
Now, the time taken by Police man = time taken by thief to get caught
⇒ (x + 900)/75 = 900/45
⇒ 45x + 45 × 900 = 900 × 75
⇒ 45x = 900 × 30
⇒ x = 27000/45 = 600 m
∴ The correct answer is 600 m.
