One of the most important and exam oriented question as it was already asked in previous year paper of 2017 in which we have to calculate the time taken by a car to reach the tower if a man observes a car from the top of a tower, which is moving towards the tower with a uniform speed. If the angle of depression of the car changes from 30o to 45o in 12 minutes.
