Expert Answer:

distance travelled in first case is = speed x time = 7.5 x 2/60 =  0.25 km 
In second interval also the distance travelled by hare = 0.25 km 
 
Total distance travelled = 0.25 + 0.25 = 0.5 km 
Total time taken for whole journey = 2 min + 2 min + 56 min = 60 min = 1 h
 
Thus, average speed = total distance travelled/ total time taken = 0.5/ 1 = 0.5 km/h
