The graph shows the relationship between distance driven and gallons of gas used. Continuous graph on a coordinate plane shows distance driven, numbered 20 to 60 along the horizontal axis, and gallons of gas used, numbered 1 to 4 on the vertical axis. Solid circles appear at points (0, 0), (30, 1), (60, 2).

Use the graph to complete the statements.

The car gets
miles to the gallon.

After the car has traveled
