Question

Which interval on the graph indicates she is stuck in a traffic jam? A B C D

Answer 1

Answer:

In interval B Kelly is stuck in a traffic jam.

Step-by-step explanation:

It is given that the graph shows Kelly traveling from home to her grandmother's house.

In the given graph x-axis represents the driving time and y-axis represents the  distance driven by Kenny.

From the given graph it is clear that the distance driven by Kenny is remain constant in the interval B.

It other intervals, the distance driven by Kenny is increasing.

Therefore, in interval B Kelly is stuck in a traffic jam.

Answer 2

Let's look at each one of the intervals.

Interval A
Interval A looks like she's going at a pretty steady pace, so Interval A is not the correct answer. 

Interval B
Interval B looks like she stays at 2.5 for an hour. That looks like a traffic jam to me! 

The correct answer is Interval B.
