Speed is how fast an object moves a certain distance within a length of time. how is speed calculated? a) distance/time b) time/distance c) velocity/time d) distance x time

I believe the answer to be A) because distance with the time it took to to reach the distance would determine how speed is to be calculated.

The answer is A) distance/time.
