A) 504 metres B) 756 metres C) 378 metres D) 630 metres

Answer 1

Answer:

The distance between the Thief and the Policeman was 400- metres.

The difference in speed of both was=(9–5)= 4Km/h= 4 x 5/18= 20/18= 10/9 metres / sec.

So 400/(10/9)=400x9/10 =360- seconds. =360/60 =6- minutes.

That is after 6- minutes the thief would have run 5 x 5/18 x 360= 500- metres, before being caught by the Police man.
