Let AB be the building and the man is standing at A.
When the car is 200m away from the building, the angle of depression is 60°
tan 60° = BD/AB = √3
⇒ 200/AB = √3
⇒ AB = 115.47 m
⇒ tan30° =BC/AB = x/115.47 = 1/√3
⇒ x = 66.67
Now, the car travels distance CD in 8 seconds
CD = BD – BC = 200 – 66.67 = 133.33 m
Speed = 133.33/8 = 16.67 m/sAttention SSC CGL Students!
