A man of a cliff observes a boat at an angle of depression of 30^0 which is approaching the shore to the point immediately beneath the observer with a uniform speed. Six minutes later, the angle of depression of the boat is found to be 60^0dot Find the time taken by the boat to reach the shore.

A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at an angle of depression of 30^(@) , which is approaching the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is found to be 60^(@) . FInd the time taken by the car to reach the foot of the tower from this point.

A man on a cliff observes a boat at an angle of depression 30^(@) which is sailing towards the shore to the point immediately beneath him. Three minutes later the angle of depression of the boat is found to be 60^(@) . Assuming that the boat sails at a uniform speed, determine how much more time it will take to reach the shore.
