Answer:
Since there is already an answer up, i am going to go in depth and show how that answer was found.
Step-by-step explanation:
We know that S=d/t, where s=speed, d=distance, and t=time, we are given 2 variables which are the distance of 20km and the time of 10 minutes.
We can plug that into our equation and we get:
S=20km/10min
simplify,
S=2km/1min
thus, the average velocity would be 2 km/min
