# Speed, distance, time

## Learning Objectives

- Calculate speed, distance and time using the speed equation.
- Analyse and interpret speed time and distance graphs.

## Lesson Description

This Maths and Science topic uses the real-life context of the British America’s Cup team INEOS TEAM UK. This topic covers interpreting distance-time graphs, drawing distance-time graphs from given data and defining speed as the distance covered in a certain time. Introduce the topic of speed, distance and time with a short starter film, discussing how boat speed depends on the wind speed and on the direction of the wind, compared to the direction the boat needs to go to the next marker. The differentiated worksheets reinforce learning objectives for this topic. The resources can be used either in sequence or flexibly as an introduction to a topic, or for a quick activity.

2.6 Recall and use these equations (average) speed = distance ÷ time, distance travelled = average speed x time.

2.7 Analyse distance/time graphs including determination of speed from the gradient.

Recall some typical speeds encountered in everyday experience for wind and sound, and for walking, running, cycling and other transportation systems.

**AQA**

The speed of a moving object is rarely constant. When people walk, run or travel in a car their speed is constantly changing.

Typical values may be taken as: walking ̴ 1.5 m/s running ̴ 3 m/s cycling ̴ 6 m/s. Students should be able to recall typical values of speed for a person walking, running and cycling as well as the typical values of speed for different types of transportation systems.

For an object moving at constant speed the distance travelled in a specific time can be calculated using the equation: distance travelled = speed × time s = v t.

If an object moves along a straight line, how far it is from a certain point can be represented by a distance–time graph.

The speed of an object can be calculated from the gradient of its distance–time graph.
