A Correct answer
Explanation

Time = Distance / Speed. New time = (2 * Distance) / (2 * Speed) = Distance / Speed = h.

AI explanation

Using the formula Time = Distance / Speed, the original time is h = D / S. For the new scenario, the time becomes 2D / 2S, which simplifies to D / S. Therefore, the new time remains h.
