Calculating Average Speed with Distance Time Graphs

Mr. Kessler explains how to read and interpret distance-time graphs, focusing on constant speed. He demonstrates how to calculate average speed using the formula distance divided by time, and emphasizes the importance of correct units and labels. The video includes examples of reading specific points on the graph and solving average speed problems, highlighting common mistakes and verification methods.

What is the formula for calculating average speed?

• Speed = Distance / Time

• Speed = Distance x Time

• Speed = Time x Distance

• Speed = Time / Distance

What is the average speed of the car at 3 seconds if the distance is 30 meters?

• 15 meters per second

• 10 meters per second

• 20 meters per second

• 5 meters per second

What is the average speed of the car at 5 seconds if the distance is 50 meters?

• 5 meters per second

• 15 meters per second

• 10 meters per second

• 20 meters per second

Why is it important to read the labels on a graph carefully?

• To understand the graph's title

• To determine the graph's color scheme

• To identify the graph's creator

• To know the units of measurement
