Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.

The answer is a. <span>It represents a linear function because there is a constant rate of change. This can be done the opposite way, but lets use minutes as x and hours as y. Every time y increases by 1, x increases by 60. This means there is a constant rate of change of 1 (rise) over 60 (run). A linear equation must have a constant rate of change.</span>
