Describe the difference between a distance-time graph showing a steady speed and one showing acceleration. 2. In which section of her journey to school is Rania moving fastest? 3. Calculate Rania's speed for section E of the graph at the top of the page.
Understand the Problem
The question focuses on understanding and analyzing the distance-time graph of Rania's journey to school. It asks for an explanation of the different sections of the graph, identifying steady speed and acceleration, as well as calculating Rania's speed in a specific section.
Answer
1. Steady speed: straight line; acceleration: curved line. 2. Section A. 3. 30 m/min.
- A distance-time graph with steady speed is a straight line with constant slope, while one showing acceleration has a curved line indicating increasing slope. 2. Rania is moving fastest in section A, where the graph is steepest. 3. The speed for section E is 30 m/min.
Answer for screen readers
- A distance-time graph with steady speed is a straight line with constant slope, while one showing acceleration has a curved line indicating increasing slope. 2. Rania is moving fastest in section A, where the graph is steepest. 3. The speed for section E is 30 m/min.
More Information
In distance-time graphs, a straight line indicates constant speed, and a curve indicates changing speed due to acceleration. Steeper lines represent higher speeds.
Tips
Don't confuse the gradient (slope) of the graph with the total distance. A steeper gradient means faster speed.
