Answer:
1. Yes
2. 60
Step-by-step explanation:
The graph is proportional because it passes an origin point.
The equation of the graph is
[tex]y = 3x \: \: (x \geqslant 0) \: \: (y \geqslant 0)[/tex]
We can find the distance when travelling in 20 minutes by substituting x = 20 in the equation.
[tex]y = 3(20) \\ y = 60[/tex]
Therefore the distance (ft) is 60.
