Answer
3 hours 30 minutes

The correct answer is 3 hours 30 minutes — Therefore the total travel time is 3 hours 30 minutes.

Step-by-step solution

  1. Convert 1 hour 30 minutes into hours: 1 hour + 0.5 hour = 1.5 hours.
  2. Add the two travel times: 2 hours + 1.5 hours = 3.5 hours.
  3. Express 3.5 hours as 3 hours 30 minutes.
  4. Therefore the total travel time is 3 hours 30 minutes.
Common mistake: Treating 30 minutes as 0.3 hour instead of 0.5 hour
