Answer
4h 30m

The correct answer is 4h 30m — Step 4: The train took 4 h 30 m to reach city Z.

Step-by-step solution

  1. Step 1: Convert every time segment to minutes: 2 h 30 m = 150 m, 15 m = 15 m, 1 h 45 m = 105 m.
  2. Step 2: Add the three parts: 150 m + 15 m + 105 m = 270 m.
  3. Step 3: Convert the total back to hours and minutes: 270 m ÷ 60 m/h = 4 h 30 m.
  4. Step 4: The train took 4 h 30 m to reach city Z.
Common mistake: Omitting the stop time or converting minutes incorrectly
