Question

Can anyone help with this problem? I've tried it at least five or six times, and I keep on getting the wrong answer. An airplane in Australia is flying at a constant altitude of 2 miles and a constant speed of 600 miles per hour on a straight course that will take it directly over a kangaroo on the ground. How fast is the angle of elevation of the kangaroo's line of sight increasing when the distance from the kangaroo to the plane is 3 miles? Give your answer in radians per minute.

Answer 1

Do you need help?

Answer 2

@asdfjkl; ??

Answer 3

Yes, I do need help. I made a right triangle and related the two sides using sine, but that doesn't seem to be the right way to answer the question. Maybe I'm differentiating incorrectly?

Answer 4

Hello again.

Answer 5
