Bob traveled

Bob traveled 20 meters to Dave's house. He arrived in 3 minutes. What was his average speed for the trip.

Correct result:

v =  0.1111 m/s

Solution:

$$\begin{gathered} s=20\text{ m } \\ t=3\text{ min}\to \text{ s}=3\cdot 60\text{ s}=180\text{ s } \\ v={\displaystyle \frac{s}{t}}={\displaystyle \frac{20}{180}}={\displaystyle \frac{1}{9}}=0.1111\text{ m/s} \end{gathered}$$
