Answer 1

Explanation:

a) Graph between point B and C is parallel to the x-axis as time is changing but distance remains the same means there is no motion.

Boojho is at rest position.

b) Motion between time 0 min to 4 min is nonuniform because the graph is not straight. It like two-line joining at point A.

c) At time 12-minute distance is 225 m and at time 8-minute distance is 150 m so speed is distance divided by the time taken

speed= 225-150/12-8 = 75m/4min = 18.75 m/min
