MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Two ships leave a port at 9 a.m. One travels at a bearing of N 530 W at 13 miles per hour, and the other travels at a bearing of S 670 W at s miles per hour. (a) Use the Law of Cosines to write an equation that relates s and the distance d between the two ships at noon. d= V 9s + 1521 + 1178 X (b) Find the speed s that the second ship must travel so that the ships are 41 miles apart at noon. (Round your answer to two decimal places.) 14.25 mi/h Show My Work (Required)
