A: Elephants can only run short distances at a time because of their considerable size and weight. They reach a top running speed of approximately 40km (25 miles) an hour.This is a speed that rivals even the fastest humans.: There are currently about 600 000 African elephants (including both the Savannah-and the Forest subspecies) and approximately 40 000 Asian elephants roaming the earth. Of these, about 20% are bred in zoos and circuses. In 1979, there were 1.3 million African elephants.
