A train travels 300 km in 2 hours at a steady speed. What is its speed?
Answer and explanation
Correct answer: B. 150 km/h
- Step 1: Speed = distance time.
- Step 2: km/h.
Answer
150 km/h.
Why not the others: 600 km/h: distance and time are multiplied. 0.007 km/h: time is divided by distance. 298 km/h: time is subtracted from distance.
