Note

In Geography we use two types of distances:

1. Absolute difference
2. Relative distance

1. Absolute difference

This is the difference in kilometres in a straight line between two points (as the crow flies).

This difference doesn't change.

2. Relative distance

This is the distance in actual travel time. The measurement unit is time. This distance may change based on:

• Mode of transport
• Infrastructure

Example

I live in Hoofddorp.

The absolute distance is 36.5 km

The distance by road is 43.12 km

Example
