Transcribed Image Text:A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 2 h per
increment, and scale for the velocity axis is 210 km per increment. (Indicate direction by the sign of the velocity.)
