In this lesson, students will explore ideas related to lengths and repeated lengths to understand properties of add ition using the graphical scale. Objectives: 1. Students will measure distances on a map using the graphical scale. 2. Students will add smaller lengths to determine longer distances. 3.
Calculate the straight line distance (as the crow flies) between cities or any two points on earth. Use your location to know any distance from where you are.
Straight-line distance otherwise known as the crow flies is the simplest way of measuring distance between two destinations. However, this distance can be calculated using different formulas based on a variety of assumptions.
We can work out the equation of a straight line, if we know two things: the gradient any point on the line The equation of a straight line is given by: y b = m(x a) where m is the gradient and (a,b) is a point on the line. The general equation of a straight line is Ax + By + C = 0 Example 1)
On most maps, a scale is usually represented as a straight line divided into several numbered units. This is called a linear scale or bar scale. It helps you to find how far one place is from another. It also helps you to measure distance along roads, railways and other linear features on the map. Figure 3.3: A linear scale
