The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n To convert 90 meters per second (m\/s)<\/strong> into miles per hour (mph)<\/strong>, we use unit conversion factors step-by-step.<\/p>\n\n\n\n 1. Convert meters to kilometers:<\/strong> 2. Convert seconds to hours:<\/strong> 3. Convert kilometers to miles:<\/strong> So, 324\u2009km\/hr\u00d71\u2009mile1.609\u2009km=201.37\u2009miles\/hr324 \\, \\text{km\/hr} \\times \\frac{1 \\, \\text{mile}}{1.609 \\, \\text{km}} = 201.37 \\, \\text{miles\/hr}<\/p>\n\n\n\n To convert speed from meters per second (m\/s) to miles per hour (mph), it is essential to follow systematic unit conversions. First, we know that 1000 meters make 1 kilometer<\/strong>, and 3600 seconds make 1 hour<\/strong>. So, to go from meters\/second to kilometers\/hour, we multiply by 3.6: 90\u2009m\/s\u00d736001000=324\u2009km\/hr90 \\, \\text{m\/s} \\times \\frac{3600}{1000} = 324 \\, \\text{km\/hr}<\/p>\n\n\n\n Next, to convert kilometers to miles, we use the known conversion that 1 mile = 1.609 kilometers<\/strong>, or conversely, 1 kilometer = 1 \u00f7 1.609 = 0.621371 miles<\/strong>. Therefore: 324\u2009km\/hr\u00d70.621371=201.37\u2009miles\/hr324 \\, \\text{km\/hr} \\times 0.621371 = 201.37 \\, \\text{miles\/hr}<\/p>\n\n\n\n This final value tells us how fast 90 m\/s is in terms of miles per hour. The correct result is approximately 201.37 mph<\/strong>, which matches option C<\/strong>.<\/p>\n\n\n\n This conversion is crucial in scientific, engineering, and international contexts where different measurement systems (SI vs. Imperial) are used. Whether calculating vehicle speeds or converting units for physics problems, being fluent with these conversion steps ensures accuracy and clarity.<\/p>\n","protected":false},"excerpt":{"rendered":" Covert 90 m\/s into miles\/hr.
