A car travels 500 m in 50 s, then 1500 m in 75 s. Calculate its average speed for the whole journey. A motorbike travels at an average speed of 12 m/s for 25 s. Calculate the distance travelled in ...

Let’s begin by visualizing all of the relationships between velocity and results using a Directed Acyclic Graph, or DAG for ...

A school bus is travelling at 4 m/s. Its velocity then increases to 12 m/s. Calculate the average velocity of the bus over the journey. Final velocity = 12 m/s. Initial velocity = 4 m/s.
