Let the height of the building be h. D the man standing on the top of the building. Now, from figure, AB = x and BC = y tan 60⁰ = h/y h = y√3 And tan 30⁰ = h/(x+y) 1/√3 = (y√3)/(x+y) 3y = x+y 2y = x y = x/2 Since, Time taken to cover a distance from A to B = 8 minutes ∴ Time taken to cover a unit distance = 8/x minutes For distance ‘y’ time taken = 8/x × y = 8/x × x/2 = 4 minutes.
