Question

Which graph could represent the following story? Trent walked from the cafeteria to his math class. After class, he walked back to the cafeteria and stopped to get a beverage from a vending machine on the way.

A) Image 1 (1st Image)
B) Image 2 (2nd Image)
C) Image 3 (3rd Image)
D) Image 4 (4th Image)

Answer 1

D) Image 4 (4th Image)

Explanation:

The maths class is away from the cafeteria so the line inclines upwards. The line then stays flat indicating the time spent in the same spot at his maths class. Then he starts heading back to the cafeteria and the line inclines downward. He then stops along the way for a drink which indicates the second flat line where he spent time in the same spot. Finally, the line inclines all the way down towards the bottom showing that he is back at the cafeteria.
