To convert from degrees to nautical miles, we multiply the departure in degrees by the cosine of the latitude. The latitude of the two places is 60\u00c2\u00b0 N, so the cosine of the latitude is $\\cos(60^\\circ) = \\frac{1}{2}$.

Option $\\text{C}$ is incorrect because it is the distance between the two places, not the departure. Option $\\text{D}$ is incorrect because it is the distance between the two places in nautical miles, but it is too small.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[654],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The longitudes of two places at latitude 60\u00c2\u00b0 N are 93\u00c2\u00b0 E and 97\u00c2\u00b0 W.
