Question

The graph shows the relationship between time and distance for Shelly's trip to work. During what time period was the car stopped?

A) 0 to 10 minutes
B) 10 to 15 minutes
C) 15 to 30 minutes
D) 20 to 25 minutes

Answer 1

Option B. 10 to 15 minutes. Hope this helps :)

Answer 2

The correct answer is B) 10 to 15 minutes.

Explanation:

We are given a graph of Time (minutes) vs Distance (miles).

This notation indicates that in the x-axis we have the time whose unit is minutes and in the y-axis we have the distance whose unit is miles.

Our graph is formed by a sequence of segments (we actually can see it).

Wherever we have a graph of Time vs Distance, the intervals of time in which the graph is parallel to the x-axis indicate us that the object is not moving. This is one possible geometric approach to the problem.

In order to answer during what time period was the car stopped, we are going to look for the parts of the graph that are parallel to the x-axis.

In the graph we can see that this occurs between the minute number 10 and the minute number 15.

Therefore, the correct option is B) 10 to 15 minutes.
