<em>The formula that represents correct variation of the formula for speed would be d = st, where d = distance traveled by an object, s = speed of the object, and t = the time taken by the object.</em>
<u>Speed is defined as the distance traveled by a moving object per the time taken by the object to complete the distance</u>. Mathematically, it is represented as:
Speed (s) = .
Hence, s =
If the formula is cross multiplied, then we will have;
