Analyzing Speed and Temperature Patterns

The video tutorial explains how to use graphs to describe relationships between quantities. It covers three examples: temperature changes in two cities, the speed of a subway train, and a race between two runners. Each example demonstrates how to interpret and sketch graphs based on verbal descriptions, focusing on understanding slopes and changes over time.

What is the primary purpose of using graphs in this lesson?

• To memorize data

• To describe relationships between quantities

• To calculate exact values

• To replace verbal descriptions

In a distance vs. time graph, what does a horizontal line indicate?

• Decreasing distance

• Variable distance

• Constant distance

• Increasing distance

How does the temperature change in Belfast, Maine, throughout the day?

• Starts high and decreases

• Fluctuates randomly

• Starts low and increases, then decreases

• Remains constant

What could be a possible explanation for the temperature pattern in Newport, Oregon?

• A sunny day

• A cold front

• A storm passing through

• A heatwave

What does a constant rate of change in speed indicate on a graph?

• A curved line

• A horizontal line

• A vertical line

• A straight line

How does the speed of the subway train change over time?

• Increases, then decreases

• Decreases, then increases

• Fluctuates randomly

• Remains constant

What is the initial speed pattern of Runner A in the race?

• Fluctuates throughout the race

• Runs at a constant speed, then stops

• Starts slow, then speeds up

• Starts fast, then slows down

How does Runner B's speed change compared to Runner A?

• Starts faster and finishes slower

• Starts slower and finishes faster

• Maintains the same speed throughout

• Starts and finishes at the same speed

What determines the winner in the race between the two runners?

• The runner with the fastest start

• The runner with the most consistent speed

• The runner who finishes first

• The runner who stops the least

What does a non-linear increase in speed indicate on a graph?

• A sudden stop

• An accelerating speed

• A decelerating speed

• A constant speed
