Maps with decimal distances<\/strong><\/h2>\n\n\n\n

key notes :<\/strong><\/p>\n\n\n\n

\ud83d\udccf What is a Map Distance?<\/strong><\/p>\n\n\n\n

Map distance is the distance between two points on a map<\/strong>.<\/p>\n\n\n\n

Usually measured in centimeters (cm) or meters (m)<\/strong> depending on the map.<\/p>\n\n\n\n

\ud83e\uddee Using Decimals in Maps<\/strong><\/p>\n\n\n\n

Sometimes, distances are not whole numbers<\/strong> \u2192 we use decimal numbers<\/strong>.<\/p>\n\n\n\n

Example: 3.5 km, 2.75 km.<\/p>\n\n\n\n

Decimals make distances more accurate<\/strong>.<\/p>\n\n\n\n

\ud83d\uddfa\ufe0f Scale of a Map<\/strong><\/p>\n\n\n\n

Scale shows how map distances relate to real distances<\/strong>.<\/p>\n\n\n\n

Example: 1 cm : 5 km<\/strong> \u2192 1 cm on the map = 5 km in real life.<\/p>\n\n\n\n

Formula:<\/strong> Real\u00a0Distance=Map\u00a0Distance\u00d7Scale\u00a0Factor\\text{Real Distance} = \\text{Map Distance} \\times \\text{Scale Factor}Real\u00a0Distance=Map\u00a0Distance\u00d7Scale\u00a0Factor<\/p>\n\n\n\n

\u2795 Adding Decimal Distances<\/strong><\/p>\n\n\n\n

When traveling multiple routes, add decimal distances<\/strong> carefully.<\/p>\n\n\n\n

Example: 2.5 km + 3.7 km = 6.2 km \u2705<\/p>\n\n\n\n

\u2796 Subtracting Decimal Distances<\/strong><\/p>\n\n\n\n

To find shorter distances between points<\/strong>, subtract decimals.<\/p>\n\n\n\n

Example: 5.6 km \u2212 2.4 km = 3.2 km \u2705<\/p>\n\n\n\n

\u2716\ufe0f Multiplying Decimal Distances<\/strong><\/p>\n\n\n\n

Sometimes, a map distance is multiplied by a scale<\/strong> to get real distance.<\/p>\n\n\n\n

Example: Map distance = 2.4 cm, Scale = 5 km\/cm \u2192 Real distance = 2.4 \u00d7 5 = 12 km<\/p>\n\n\n\n

\u2797 Dividing Decimal Distances<\/strong><\/p>\n\n\n\n

Used when finding distance per unit<\/strong>.<\/p>\n\n\n\n

Example: 15 km \u00f7 3 = 5 km per route<\/p>\n\n\n\n

\ud83d\udccc Tips for Accuracy<\/strong><\/p>\n\n\n\n

Always align decimal points<\/strong> when adding or subtracting.<\/p>\n\n\n\n

Check units<\/strong>: cm on map vs km in real life.<\/p>\n\n\n\n

Round decimals only when necessary<\/strong>.<\/p>\n\n\n\n

\ud83c\udfaf Practice Makes Perfect<\/strong><\/p>\n\n\n\n

Measure distances on any map and convert using scale<\/strong>.<\/p>\n\n\n\n

Use decimal operations to calculate total, remaining, or per unit distances<\/strong>.<\/p>\n\n\n\n
