Question

The proportional relationship between the distance driven and the amount of time driving is shown in the following graph. Which statements about the graph are true?

Choose all answers that apply:
A. The y-coordinate of point AAA represents the distance driven in 444 hours.
B. The distance driven in 1 hour is 80km.
C. None of the above

Answer 1

The distance driven in 1 hour is 80 km. Therefore, option B is the correct answer.

Step-by-step explanation:

The given time graph shows the proportional relationship between the distance driven and the amount of time driving.

If an object moves along a straight line, the distance traveled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

From the graph, we can see that object A moved 400 km in 5 hours.

So, in 1 hour the distance traveled by the object =400/5

=80 km

Therefore, option B is the correct answer.
