For an RF to be meaningful, both the map distance and the ground distance must be expressed in the same units.<\/p>\n\n\n\n<p>The given verbal scale is &#8220;4 cm to 1 km&#8221;. This means that a length of 4 centimeters on the map represents an actual distance of 1 kilometer on the ground.<\/p>\n\n\n\n<p>To calculate the RF, we need to convert the ground distance (1 km) into the same unit as the map distance (centimeters). We know the following conversion factors:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 kilometer (km) = 1,000 meters (m)<\/li>\n\n\n\n<li>1 meter (m) = 100 centimeters (cm)<\/li>\n<\/ul>\n\n\n\n<p>Therefore, to convert 1 kilometer to centimeters, we multiply:<br>1 km = 1,000 m * 100 cm\/m = 100,000 centimeters.<\/p>\n\n\n\n<p>Now we can express the scale as a ratio of map distance to ground distance using the same units:<br>Map distance : Ground distance<br>4 cm : 100,000 cm<\/p>\n\n\n\n<p>The RF is typically written with a numerator of 1. To achieve this, we divide both sides of the ratio by the map distance (4):<br>(4 cm \/ 4) : (100,000 cm \/ 4)<br>1 cm : 25,000 cm<\/p>\n\n\n\n<p>When the units are the same, they cancel out, leaving a dimensionless ratio or fraction. The Representative Fraction is therefore <strong>1:25,000<\/strong> or 1\/25,000. This means that any unit of measurement on the map represents 25,000 of the same units on the ground.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the RF when the Verbal scale is 4 cm to 1 km The correct answer and explanation is: Okay, let&#8217;s calculate the Representative Fraction (RF) from the verbal scale 4 cm to 1 km.
