Answer :
AVERAGE SPEED OF A ANIMAL DIFFER FROM ANIMAL TO ANIMAL. LIKE IF YOU SEE A CHEETAH WHOSE SPEED IS 72KM/HR.BUT THE SPEED OF A SEA HORSE IS 0.00016KM/HR. SO I THINK THE AVERAGE SPEED DEPENDS UPON A PARTICULAR ANIMAL.
average speed of wild animals is more than domestic animals.for eg cheetah its 73km/hr and for adog its 48km/hr.average speed depends on the nature of the animals
