This process involves multiplying the original value by a series of conversion factors, which are fractions equal to one, to systematically cancel out the old units and introduce the new ones.<\/p>\n\n\n\n<p>The initial speed is 8 feet per hour. We can write this as a fraction: (8 feet \/ 1 hour).<\/p>\n\n\n\n<p>First, we will convert the distance unit from feet to miles. According to the provided chart, 1 mile is equal to 5280 feet. To cancel out &#8220;feet&#8221; from the top of our fraction, we need a conversion factor with &#8220;feet&#8221; in the bottom. Therefore, we multiply by (1 mile \/ 5280 feet).<\/p>\n\n\n\n<p>Next, we need to convert the time unit from hours to months. This is a two-step conversion. First, we convert hours to days. The chart states that 1 day equals 24 hours. To cancel &#8220;hours&#8221; from the bottom of our fraction, we multiply by a factor with &#8220;hours&#8221; on top: (24 hours \/ 1 day).<\/p>\n\n\n\n<p>Then, we convert days to months. The chart provides the approximation that 1 month is about 30 days. To cancel &#8220;days&#8221; from the bottom of our new fraction, we multiply by a factor with &#8220;days&#8221; on top: (30 days \/ 1 month).<\/p>\n\n\n\n<p>Now we can set up the complete equation:<br>(8 feet \/ 1 hour) \u00d7 (1 mile \/ 5280 feet) \u00d7 (24 hours \/ 1 day) \u00d7 (30 days \/ 1 month)<\/p>\n\n\n\n<p>Multiplying the numbers across the top and bottom gives us:<br>(8 \u00d7 1 \u00d7 24 \u00d7 30) miles \/ (1 \u00d7 5280 \u00d7 1 \u00d7 1) months = 5760 miles \/ 5280 months<\/p>\n\n\n\n<p>Performing the division:<br>5760 \u00f7 5280 \u2248 1.0909&#8230; miles per month<\/p>\n\n\n\n<p>The final step is to round the answer to the nearest tenth. The tenths digit is 0, and the digit to its right is 9. Since 9 is 5 or greater, we round the tenths digit up to 1.<\/p>\n\n\n\n<p>The final speed is 1.1 miles per month.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-2089.jpeg\" alt=\"\" class=\"wp-image-271729\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Correct Answer and Explanation is: Correct Answer: 1.1 miles per month This problem requires converting a speed from feet per hour to miles per month using a method called dimensional analysis.
