Question : 26 of 40

Marks: +1, -0

A policeman saw a thief at a distance of 200 m. The policeman and the thief started running at the same time. If the policeman runs at a speed of

4 1/6

m per second and the thief at a speed of

3 1/3

m per second, after what time the policeman will catch the thief?

Solution:

Suppose the policeman will catch the thief after t seconds
then,

({25}/6-{10}/3)t

= 200
⇒

5/6 t

= 200
∴ t =

{200×6}/5

= 240 s
= 4 min.
