Hey Ricky, good to see you again.
Here are the answers to the homework questions based on the map:
1. Name the type of scale that is shown on this extract.
The type of scale shown on this map extract is a bar scale (also known as a graphic scale or linear scale).
2. Calculate the distance in kilometres from Durban to Polokwane using the scale in the map extract.
- Step 1: Determine the map scale from the bar.
- The bar scale shows that approximately 3.5 cm on the map represents 800 km in reality.
- Thus, the scale factor is 3.5cm800km.
- Step 2: Measure the straight-line distance between Durban and Polokwane on the map.
- The measured distance on the map is approximately 2.5 cm.
- Step 3: Calculate the actual distance using the scale factor.
Actualdistance=2.5cm×3.5cm800km
Actualdistance=3.52000km≈571.43km
The distance from Durban to Polokwane is approximately ∗571.43km∗.
3. Calculate the distance in metres from Karkloof to Johannesburg.
- Step 1: Measure the straight-line distance between Karkloof and Johannesburg on the map.
- The measured distance on the map is approximately 1.5 cm.
- Step 2: Calculate the actual distance in kilometers.
Actualdistance=1.5cm×3.5cm800km
Actualdistance=3.51200km≈342.86km
- Step 3: Convert the distance from kilometers to meters.
Actualdistanceinmeters=342.86km×1000m/km=342860m
The distance from Karkloof to Johannesburg is approximately ∗342860m∗.
4. Calculate the distance in kilometres from Polokwane to Cape Town. Is this an example of a large-scale map or small-scale map?
- Step 1: Measure the straight-line distance between Polokwane and Cape Town on the map.
- The measured distance on the map is approximately 4.5 cm.
- Step 2: Calculate the actual distance in kilometers.
Actualdistance=4.5cm×3.5cm800km
Actualdistance=3.53600km≈1028.57km
The distance from Polokwane to Cape Town is approximately ∗1028.57km∗.
- Step 3: Determine the map scale type.
- This map covers a very large geographical area, encompassing multiple countries in Southern Africa. Maps that show large areas with less detail are classified as small-scale maps. Therefore, this is an example of a small-scale map.
5. Is this an example of a large scale map or small scale map?
This map is an example of a small-scale map. It depicts a vast region (Southern Africa) and consequently shows less detail for specific locations.
