Step-by-step explanation:
given that a balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon
The distance of the boat from the balloon measured horizontally in the I position = 800 tan 20
After 25 seconds distance of the boat from the balloon measured horizontally in the II position
= 800 tan 65
Distance moved by the boat in 25 seconds
=
Speed of the boat per second =
53.702 feet per second is the speed of boat
