Answer
4 km/h

The correct answer is 4 km/h — Divide 6 km by 1.5 h to get speed = 4 km/h.

Step-by-step solution

  1. Convert time to hours. 1 hour 30 minutes = 1 + 30/60 = 1.5 hours.
  2. Use the formula for speed: speed = distance ÷ time.
  3. Divide 6 km by 1.5 h to get speed = 4 km/h.
Common mistake: Failing to convert minutes into decimal hours
