Acar travels 10 meters north, then 25 meters south, then 30 meters north. the trip takes 15 seconds.
a- what is its average speed?
b-what is its average velocity?

Why is your question in Biology section, it should be in mathematics or in physics but that's OK

The answer of A is - 21.6666666666 or 21.7

The answer of B is - 21.6666666666 or 21.7

the answer of A and B are equal because speed and velocity is the same thing

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day
