A cyclist rides at 36 km/h. What is this speed in meters per second?
Answer and explanation
Correct answer: A. 10
- Step 1: 1 km = 1000 m and 1 h = 3600 s.
- Step 2: 36 x 1000 / 3600 = 10 m/s (divide km/h by 3.6).
Answer
10.
Why not the others: 129.6 multiplies by 3.6 instead of dividing; the other values use an unrelated factor.
