A nomadic pastoral group travels 150 km from their winter pasture to summer pasture, covering 5 km per hour. How many hours will they spend on the journey?
Answer
30
The correct answer is 30 — Compute (t=150/5=30) hours.
Step-by-step solution
- Apply the formula (t=\frac{d}{v}).
- Substitute (d=150) km and (v=5) km/h.
- Compute (t=150/5=30) hours.
Common mistake: Using distance instead of speed or forgetting to divide
Concept tested: Speed-distance-time calculation
