Question

if each grid line stands for 400 meters, how far is it from the science lab to the garbage dump?

Explanation:

Step1: Find the distance on the grid

Count the number of grid - lines between the science lab and the garbage dump. The science lab is at \((-3,1)\) and the garbage dump is at \((-3, - 2)\). The vertical distance between them is \(|1-(-2)|=3\) grid - lines.

Step2: Calculate the actual distance

Since each grid - line stands for \(400\) meters. Multiply the number of grid - lines by \(400\). The formula for the distance \(d\) is \(d = 400\times n\), where \(n\) is the number of grid - lines. Substitute \(n = 3\) into the formula: \(d=400\times3\).

Answer:

\(1200\) meters
