During a relay race, you run the first leg of the race, a distance of 2.2 10² m to the north, in 22.18 s. You then run the same distance back to the south in 24.00 s in the second leg of the race. Suppose the positive y axis points to the north. (Express your answers in vector form).

a) What is your average velocity for the first leg of the relay race?

(b) What is your average velocity for the entire race?
