the distsnce between two places show on a map is 2.5cm if the scale of themap is 1cm to 5km how much is the actual distance between these places?​

Answer» <html><body><p><strong>Answer:</strong></p><p>It is simply calculation of scale,and scale of the map is <a href="https://interviewquestions.tuteehub.com/tag/defined-947013" style="font-weight:bold;" target="_blank" title="Click to know more about DEFINED">DEFINED</a> as “ratio of a distance on the map to the <a href="https://interviewquestions.tuteehub.com/tag/corresponding-935567" style="font-weight:bold;" target="_blank" title="Click to know more about CORRESPONDING">CORRESPONDING</a> distance on the ground.”</p><p></p><p>Scale of map=distance on the map/distance on the ground.(unit of map and ground distance must be same.)</p><p></p><p>According to <a href="https://interviewquestions.tuteehub.com/tag/question-25051" style="font-weight:bold;" target="_blank" title="Click to know more about QUESTION">QUESTION</a>,1 cm on the map distance equal to 5 km on the ground distance.</p><p></p><p>Step 1:-convert one of them in single unit, either cm convert into km or vice <a href="https://interviewquestions.tuteehub.com/tag/versa-1444865" style="font-weight:bold;" target="_blank" title="Click to know more about VERSA">VERSA</a>.</p><p></p><p>(I converted km into cm)</p><p></p><p>5km*1000=5000m</p><p></p><p>5000m*100=500000cm.
