The AVERAGE velocity for the 20 minute interval is zero, since you end up where you started.

4+4.5+2=10.5km in total.
Trip takes twenty minutes. So if you take 8.75 meters times that by 20 then times the answer of that by 20 you get 10500 meter which is 10.5 km.
The answer is 8.75 m/s

1. set it up:
s=d/t --> s=(2+4+4.5)km/ 20min
2. Convert to meters/ seconds
s= 10.5km/20 min x 1000m/km x 1min/60s= 8.75 m/s
s=d/t --> s=(2+4+4.5)km/ 20min
2. Convert to meters/ seconds
s= 10.5km/20 min x 1000m/km x 1min/60s= 8.75 m/s
