a race car completes 10 laps around an oval track. which of the following pairs of quantities concerning its motion would both have values of zero?

a)displacement, avg velocity

B)avg speed, avg acceleration

c)distance, avg speed

d)avg speed, avg velocity

e) displacement, avg speed

my guess is A since its an oval track the person keeps running to the same spot 10 times where they originally started...but i'm not sure why velocity could you explain please?

correct, A. Avg velocity=(finalposition-intialpositon)/time

final and initial postion are the same.
