A straight highway leads to the foot of a tower . A man standing on the top of
the tower spots a van at an angle of depression of 30 degree. The van is approaching
the tower with a uniform speed. After 6 minutes, the angle of depression of the van
is found to be 60 degree. How many more minutes will it take for the van to reach the
tower?
