A cyclist rides at 108 km/h. What is this speed in meters per second?
Answer and explanation
Correct answer: D. 30
- Step 1: 1 km = 1000 m and 1 h = 3600 s.
- Step 2: 108 x 1000 / 3600 = 30 m/s (divide km/h by 3.6).
Answer
30.
Why not the others: 388.8 multiplies by 3.6 instead of dividing; the other values use an unrelated factor.
