A cyclist travels 120 meters in 36 seconds. What is his speed in m/s and in km/h?

Step-by-step solution

1. Compute speed in m/s: $120\text{ m}÷36\text{ s}=\frac{10}{3}\text{ m/s}=3.33\text{ m/s}$.
2. Convert to km/h by multiplying by 3.6: $3.33\text{ m/s}\times 3.6=12\text{ km/h}$.
3. Thus the speed is $3.33\text{ m/s}$ and $12\text{ km/h}$.
