Boojho goes to the football ground to play football. The distance-time graph of his journey from his home to the ground is given as a figure.

$(a)$. What does the graph between points B and C indicate about the motion of Boojho?
$(b)$. Is the motion between 0 to 4 minutes uniform or non-uniform?
$(c)$. What is his speed between 8 and 12 minutes of his journey?"

$(a)$. The graph between B and C is a horizontal line Which indicates that Boojho is at rest. There is no motion fro B to C.

$(b)$. Between 0 to 4 minutes, the graph is not a straight line. So, there is no uniform motion.

$(c)$. Speed between 8 to 12 minutes $=\frac{distance}{time}$

$=\frac{225\ m-150\ m}{12\ minute-8\ minute}$

$=\frac{75\ m}{4\ minute}$

$=13.75\ m/minute$
