Answer:

v = 6.89 [m/s]

velocity = 0

Explanation:

To solve this problem we must use the definition of speed which is defined by the following expression of physics, such as the relationship between distance and time.

v = x/t

where:

v = speed [m/s]

x = distance = 400 [m]

t = time = 58 [s]

v = 400/58

v = 6.89 [m/s]

The velocity is a vector, since the racing car moves in circles IE its movement started where it ended, its velocity is zero.
