Answer:

Distance travelled in the first 2 min

= speed × time

= 7.5 kmph × (2/60)

= 15/60 km

Distance travelled in next 56 min

= 0 km as he was sleeping

Again distance in last 2 min

= 7.5 mph × (2/60 hr)

= 15/60 km

So, total distance travelled = (15+0+15)/60

= 30/60 km

= 0.5 km

total time taken = 2+56+2 min = 60

= 1 hr

So, as average speed

= total distance travelled/ total time taken

So V avg = 0.5 km/hr

= 0.5 km/hr is the average speed of the hare.
