Finding Speed Using Distance-Time Graphs

What is represented on the y-axis of a distance-time graph?

• Time in seconds

• Distance in meters

• Speed in meters per second

• Acceleration in meters per second squared

How does the slope of the line on a distance-time graph relate to speed?

• A steeper slope indicates a slower speed

• A steeper slope indicates a faster speed

• The slope does not relate to speed

• A flatter slope indicates a faster speed

What conclusion can be drawn if a distance-time graph has a steeper slope?

• The object is moving slower

• The object is moving faster

• The object is not moving

• The object is accelerating

What does a flat segment on a distance-time graph indicate?

• Constant speed

• Acceleration

• No movement

• Deceleration

If an object moves from 0 to 2 kilometers in 2 hours, what is its speed?

• 2 kilometers per hour

• 0.5 kilometers per hour

• 4 kilometers per hour

• 1 kilometer per hour

What does it mean if the slope of a segment on a distance-time graph is constant?

• The object is accelerating

• The object is not moving

• The object is decelerating

• The object is moving at a constant speed

If an object moves back to its starting point on a distance-time graph, what can be inferred?

• The object is accelerating

• The object is decelerating

• The object is moving at a constant speed

• The object is at rest
