A bat flew 90 kilometers in one evening, returning to its cave after 3 hours.
What was the bat's average speed? A) 30 km/h B) 60 km/h C) 90 km/h D) 270 km/h

Sorry im a little late. I am as well trying to look this up. But i believe you divide 90 by 3 which would give you 60 km/h. So the answer will be B.)

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
