What is the symbol commonly used for distance in equations?

Explanation:
Distance is a scalar quantity that tells how far something has moved, regardless of direction. In equations, we use letters to label these quantities, and the letter d is commonly used to represent distance. This helps keep distance separate from other quantities: velocity is v, and time is t. The letter s is often used for displacement, which includes direction (a vector) or, in some contexts, for arc length, so it isn’t the standard symbol for distance. So using d for distance keeps the meaning clear and consistent in basic formulas.
