Which graph could represent a car that begins by increasing its speed, then travels at a constant speed, and then decreases its speed, as time increases?

A graph with time (minutes) on the horizontal axis and speed (miles per minute) on the vertical axis. Both axes are unnumbered. The speed begins at 0, goes up at first, is steady for a while, and then goes down over time.

Answer:

A

Explanation:

If you read your own question, you find that it answers itself.

The problem statement tells you that speed ...

... increasing its speed, constant speed, then decreases

And it tells you the graphs show ...

(a) begins at 0, goes up, is steady for a while, and then goes down

(b) begins in the middle, goes down, is steady, and then goes up

(c) begins at 0, goes up, goes down, and then is steady

___

The first graph has the increasing, steady, decreasing pattern you're looking for.
