Convert 18 km/h into metres per second.
Answer and explanation
Correct answer: C. 5 m/s
- Step 1: Divide km/h by 3.6. Step 2. 18 ÷ 3.6 = 5 m/s. Answer: 5 m/s. Why not the others: 64.8 m/s results from having multiplied by 3.6 instead of dividing. 3 m/s results from having divided by 6. 0.018 m/s results from having only divided by 1000.
