A straight highway leads to the foot of ...

A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at angle of depression of `30^0,` which is approaching to the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is found to be `60^0dot` Find the further time taken by the can to reach the foot of the tower.
