A graph of Isaac’s bike ride with time on the horizontal axis and distance (km) on the vertical axis. A straight line sloping up and to the right connects the points (8 am, 0) and (10:00 am, 40). There is a horizontal line connecting (10:00 am, 40) and (10:30 am, 40). A sloped line connects (10:30 am, 40) and (1:30 pm, 160).

Use the diagram to answer the following question:

How can you describe Isaacs movement from 10:00 am to 10:30 am?

Question 1:

To describe Isaac's movement from 10:00 am to 10:30 am:

Response: Isaac is not moving.

Question 2:

To determine during which segment of the trip Isaac is moving with the greatest velocity, we need to examine the slopes of the segments:

  • Segment A: 8 am to 10 am (0 km to 40 km) - This is a sloped line (indicating movement).
  • Segment B: 10 am to 10:30 am (40 km) - This is a horizontal line (indicating no movement).
  • Segment C: 10:30 am to 1:30 pm (40 km to 160 km) - This is also a sloped line.

The slope (velocity) is steeper for Segment C than for Segment A (because it covers more distance over the same time).

Response: Segment C.

Question 3:

Match each word to its correct description.

  1. Displacement: the direct length between the starting position and its ending position.
  2. Distance: the total length of the path traveled, regardless of direction.
  3. Velocity: a vector quantity: 200m to the left.
  4. Speed: the rate of distance covered over time or magnitude of velocity.
