Question 1088173: A hot air balloon is released into the air. During its straight ascent, the angle of elevation was 15� and, 3 minutes later, the angle of elevation increased 20�. How fast is the balloon traveling, in km/h, if the angle measurements were taken 300m away from the launch site?

.

1.  The distance (height) is  H = 300*tan(20�) - 300*tan(15�) meters, 0r 0.3*(tan20�)-tan(15�)) kilometers.  Calculate.


2.  The time is T =  =  of an hours.


3.  The averaged rate of traveling is   =  = 6*(tan(20�) - tan(15�)) kilometers per hour.

You complete all calculations.
