Acceleration is defined in terms of changes in velocity. You can have equal acceleration values at any velocity.
The acceleration produced by a given force upon a given mass DOES depend slightly upon velocity, according to the special theory of relativity. However, at the low speeds that you have mentioned, the difference is negligible.
