A man is observing from the top of tower a boat speeding towards the tower from a certain point A, with uniform speed. At that point, angle of depression of boat with man’s eye is 30° (ignore man’s height). After Sailing for 20 seconds, towards the base of tower (same level as of water), the boat has reached a point B, where angle of depression is 45°. Then time (in seconds) taken by boat from B to reach base of tower is: ๐ฒPW App Link - https://bit.ly/YTAI_PWAP ๐PW Website - https://www.pw.live
