An express train of length \( 150\,\mathrm{m} \) travels at the constant speed of \( 144\,\mathrm{kph} \). On a parallel track in the opposite direction travels a freight train of length \( 240\,\mathrm{m} \) at the constant speed of \( 90\,\mathrm{kph} \). How long does it take for trains to pass each other?
\( 6\,\mathrm{s} \)
\( 1.\overline{6}\,\mathrm{s} \)
\( 7.\overline{2} \)
\( 26\,\mathrm{s} \)
