A night bus leaves at 22:45 and arrives at 07:05 the next morning. How long does the journey take?

Answer and explanation

Correct answer: D. 8 h 20 min

  1. Step 1: From 22:45 to midnight is 1 h 15 min.
  2. Step 2: Add the time after midnight, 7 h 5 min, to get 8 h 20 min.
Answer
8 h 20 min.
Why not the others: 15 h 40 min: the hours and minutes were subtracted separately, ignoring the change of day. 9 h 20 min: one hour was added by mistake. 7 h 20 min: one hour was subtracted by mistake.
