Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If a train travels 800 kilometers in 6 hours, what is its average speed?

Back

Front

What is the formula to find distance?

Back

Distance = Speed x Time.

Front

What is the significance of a graph in representing motion?

Back

Graphs visually represent the relationship between distance and time, helping to understand the speed and acceleration of an object.
