Which of the following is the correct formula for instantaneous velocity?

(a) v = dx/dt

(b) v = x/t

(c) v = xt

(d) v = t/x

This question was posed to me in an online quiz.

My doubt stems from Straight Line Motion in section Motion in a Straight Line of Physics – Class 11

Correct answer is (a) v = dx/dt

Explanation: The correct formula is v = dx/dt. Instantaneous velocity is the velocity of the object at a given time instant. v = x/t is the formula for average velocity.
