Bob traveled

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

Result

v =  0.111 m/s

Solution:

s=20 m t=3 min=3⋅ 60 s=180 s  v=st=20180≐19≐0.1111≐0.111 m/ss=20 \ \text{m} \ \\ t=3 \ min=3 \cdot \ 60 \ s=180 \ s \ \\ \ \\ v=\dfrac{ s }{ t }=\dfrac{ 20 }{ 180 } \doteq \dfrac{ 1 }{ 9 } \doteq 0.1111 \doteq 0.111 \ \text{m/s}
