An object moves along a straight line so that after t minutes, its distance from its starting point is


D(t) 10t + 5 t + 1 - 5 meters.


a. At what velocity is the object moving at the end of 4 minutes?


b. How far does the object actually travel during the fifth minute?

D(t) 10t + 5 t + 1 - 5 meters.
