The Enterprise's warp core goes offline. The ship is reduced to impulse power. Sulu informs Kirk that they are twenty minutes from Qo'noS. How far is the ship from Qo'noS?

(Impulse Drive) So, using that statement, is it possible to estimate the distance between the ship and the planet? If so, what is the distance?
