A boy is cycling at a constant speed along a straight road to his school. The postions of the boy after fixed time intervals are observed.
a. What type of positiontime graph can be expected for the motion of the bicycle?
b. How can the average velocity of the bicycle be calculated?
c. How is the average speed of the bicycle related to its average velocity?
A)constant velocity/positive velocity graph
B)I don't know
C)The average speed is the absolute value of the average velocity.

a) doesnt answer the question.
b) average speed=distance/time
c)correct 
I don't know what they're looking for then

the bicycle is moving in a positive direction at a constant speed?

a. Type of graph: straight line, parabola, log?

straight line graph
