Distance-Time Graphs and Speed Quiz

Interpreting Distance-Time Graphs and Calculating Speed

• The video covers interpreting distance-time graphs, reading, redrawing, and interpreting them.

• It is important to have an awareness of speed, distance, and time to understand distance-time graphs.

• The axes of a distance-time graph show distance on the y-axis and time on the x-axis.

• Reading a distance-time graph involves identifying the start and end points of a journey and any stops made.

• To find the time a journey started, locate the beginning of the graph on the x-axis.

• To calculate the distance from the start point to a stop, read the y-axis at the point where the journey stops.

• To find the time spent at a stop, locate the flat line on the graph and read the time at the start and end points.

• Calculating average speed involves using the formula speed = distance/time.

• When calculating speed, ensure that all units are consistent (e.g., kilometers per hour).

• To complete an incomplete distance-time graph, calculate the speed for the missing section using the formula speed = distance/time.

• To calculate speed for a specific time period, ensure that the chosen period is indicated on the graph.

• Reading and interpreting distance-time graphs involves careful attention to detail and understanding of the relationships between distance, time, and speed.Solving Distance-Time Graph Problems: Finding Average Speed and Completing Graphs

• To convert minutes to kilometers per hour, divide the distance by 0.5.

• To complete a distance-time graph, find the time it takes to travel a certain distance using the speed-distance-time formula.

• To convert hours to minutes, multiply the value by 60.

• When finding the time it takes to travel a certain distance, make sure to show the working out.

• To calculate average speed, use the formula distance divided by time.

• The average speed can be in kilometers per hour or any other unit of distance per unit of time.

• In order to complete a distance-time graph, connect the points using a ruler and pencil.

• When completing a graph, make sure to label the units of distance and time.

• To find the average speed of a journey, divide the distance by the time and make sure the units are consistent.

• There are different methods to approach distance-time graph problems, such as dividing in minutes and converting back to hours.

• It is important to show the working out and label the units when solving distance-time graph problems.

• Practice and familiarity with the formulas and methods are key to solving distance-time graph problems successfully.
