Look at the speed time graphs below showing how the speed of a swimmer changes as she swims the length of the pool (mps = metres per second)

Which graph represents someone who has swam 50m? Explain how.

Answer 1

Graph I

Explanation:

The distance equals the area under the graph of a speed-time graph.

`2 * 25=50`

Answer 2

Graph 1
