A person is watching NASA launch a rocket from a distance of 3 miles
away from the launch station. After a few minutes, the person sees the
rocket through their binoculars and estimates the angle of elevation to be
10 degrees. 10 minutes later, the person looks through their binoculars
again, finds the rocket and notices that the angle of elevation has increased
to 60 degrees. Find the number of miles, to the nearest tenth, the rocket
has flown in that 10 minute time frame.
