A balloon is now stuck at a tree 280meters away from the ground. The balloon is observed by the crew of boat as they look upward at an angle of 25 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon. How fast was the boat traveling?

well, the distance traveled by the boat is found using
d = 280 cot25° - 280 cot 65°
speed = distance/time
d = 280 cot25° - 280 cot 65°
speed = distance/time
