Marks: +1, -0

A 222 metre long train crosses a pole in 6 seconds. The same train crosses a man running in the same direction in 10 seconds. What will be the speed of man ?

15 m/sec
17 m/sec
18 m/sec
14 m/sec
None of these

Validate

Solution:

Speed of train =

{222}/6

= 37 m/sec
If the speed of man be x m/ sec. then

{220}/{37-x}

= 10
⇒ 220 = 370-10x
⇒ 10x=370-220 = 150
⇒ x= 15m/sec
