A clock has 75 ~cm , 60 ~cm long second hand and minute hand respectively. In 30 minutes duration the tip of second hand will travel x distance more than the tip of minute hand. The value of x in meter is nearly (Take =3.14 ) :

Options

  1. A140.5
  2. B118.9
  3. C139.4
  4. D220.0

Correct answer

C. 139.4

Step-by-step solution

aligned x _ = & r _ = & 60 100 ~m . x _ second & =30 2 r _ second & =30 2 75 100 x = & x _ second - x _ = & 139.4 ~m aligned
