Two posts of heights 20 m and 10 m are 60 m apart, as shown in the figure. Food grains are continuously distributed between the two posts. A crow sitting on top of the taller post wants to pick up a grain and sit on the other post. What should be the distance of the grain it picks from the bottom of the taller post to minimize the total flight length?

Options

  1. A30 m
  2. B50 m
  3. C40 m
  4. D20 m

Correct answer

C. 40 m

Step-by-step solution
