Average Speed Formula: s = d/t

Where,

's' represents average speed,
'd' represents total distance, and
't' represents total time

anonymous · Answer

The answer is not D. @CREEPYMLPMASTER Because you are supposed to divide distance by time to get the average speed. And you divided time by distance to get an incorrect answer.
