A cyclist travels 150 m in 12 s. What is her average speed?
Answer and explanation
Correct answer: C. 12.5 m/s
- Step 1: Average speed = distance ÷ time.
- Step 2: 150 ÷ 12 = 12.5 m/s.
Answer
12.5 m/s.
Why not the others: 1800 m/s: the values were multiplied. 0.08 m/s: the time was divided by the distance. 138 m/s: the values were subtracted.
