Question

A truck travels from a factory to a gas station in 4 minutes. It stops at the gas station for 2 minutes. The truck then returns to the factory in 4 minutes. Which graph best represents the distance, y, in miles, of the truck from the factory after a certain amount of time, x, in minutes?

Explanation:

The first phase of the journey is f. This is where the truck travel for 4 minutes before reaching the gas station. The slope is positive because as time is increasing, distance covered is also increasing.

The truck stopped at the gas station for 2 minutes. This portion of the graph has a zero slope because as time increases, distance covered is constant.

The slope of the last portion of the graph is negative because as the time increases distance decreases as the truck returns to the factory.

Note that the journey took a total of 10 minutes.
