Question

The graph shows how the distance an object traveled changed over time.

Between which two points was the object traveling at the greatest speed?





A.
between points C and D because that slope is the steepest


B.
between points A and B because that segment is the longest


C.
between points B and C because that segment is horizontal


D.
between points A and B because that slope is the steepest

Answer 1

I believe the correct answer from the choices listed above is option D. The points where the object is traveling at the greatest speed would be between points A and B because that slope is the steepest. The slope of this graph indicates speed since it will have the units of distance per time. The steeper the line is , the greater the value of the slope which would mean faster speed.
