Exploring Distance: Time Graphs in Mathematics

What is the primary purpose of the video tutorial?

• To learn about different types of exercises

• To explore various sports activities

• To teach about distance-time graphs and get fit

• To understand the importance of a balanced diet

What does the horizontal axis (x-axis) represent in a distance-time graph?

• Acceleration in meters per second squared

• Distance in meters

• Speed in meters per second

• Time in seconds

How do you calculate speed from a distance-time graph?

• Speed = Time / Distance

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Distance + Time
