An aerial survey drone completes a journey in three stages.
| Stage | Distance travelled | Time taken |
|---|---|---|
| Flies along a pipeline | 1.2 km | 80 s |
| Remains stationary while recording data | 0 m | 25 s |
| Flies to its landing point | 450 m | 30 s |
Calculate the average speed of the drone for the complete journey.
96 exam-style questions on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration, covering 2.2.1 Speed and distance–time graphs, 2.2.2 Acceleration and the uniform-acceleration equation, 2.2.3 Velocity–time graphs, and 2.2.4 Measuring speed, typical speeds and free-fall acceleration. Each one has a worked solution and a mark scheme showing where the marks go.
