Two straight roads diverge from an intersection at an angle of 60. Two cars leave the intersection
Question:
Two straight roads diverge from an intersection at an angle of 60°. Two cars leave the intersection at the same time, the first traveling down one road at 40 mi/h and the second traveling down the other road at 60 mi/h. How fast is the distance between the cars changing after half an hour? [Hint: Use the Law of Cosines (Formula 21 in Appendix D).]
