Finally, the bus arrived. Joe jumped on and gave the driver his fare. As he sat down, he checked to make sure that he had enough
money for a ticket. Last week Joe had seen a western called Trail of the Seven Sioux. He didn't know what was showing this week. The bus was behind schedule
, and Joe was afraid he would be late--but when he got there, he didn't have to wait in line. He found a good seat just as the lights dimmed.
What is a schedule?
A schedule is simply a plan to be somewhere or do something. From the passage, we can see that the context in which the word "schedule" was used is talking about the bus being behind the planned time it was supposed to take off.
