3-A particle moves along a horizontal path with a velocity of v = (3t2-6 t) m/s, where t is the time

3-A particle moves along a horizontal path with a velocity of v = (3t2-6 t) m/s, where t is the time in seconds. If it is initially located at the origin , determine the distance traveled in 3.5sthe particle’s average velocity average speed during the time interval.
