The problem describes a race between two aircraft along a straight-line route with a distance of 44 km. The first aircraft (labeled "二郎神") starts earlier and rests after 2 seconds, while the second aircraft (labeled "孙悟空") starts later and chases. The problem asks for the values of a, b, and c, related to the distance between the two aircraft (y in kilometers) and the time taken (t in seconds), which is visualized in the given graph.

Let's break this down:

1. The aircrafts are moving along a straight route, and we are given a graph representing the distance between the two (y) over time (t).
2. The graph has three main points where the distances change: a, b, and c, which correspond to specific moments in time.

Given the graph:

• The horizontal axis represents time (t in seconds).
• The vertical axis represents the distance between the two aircrafts (y in kilometers).
• The graph shows a peak at point b, then the distance decreases at point c.

To solve for a, b, and c, we would typically need to calculate or deduce the exact times and distances based on the graph. Based on the provided diagram, here are possible inferences:

• The distance between the two aircraft reaches 4 km at a (point where the aircrafts are closest).
• The maximum distance of separation occurs at b (perhaps at 11 seconds, as marked on the graph).
• Point c shows another critical point in time when the distance changes again.

To find precise values for a, b, and c, you would need to either calculate based on more given numerical relationships or assumptions from the graph data. It seems that the graph indicates the distance vs. time for the race.

Would you like me to perform any specific calculations or provide more details on how to interpret the graph further? Feel free to ask for any clarifications!
