One afternoon, a student will return home after attending lectures calculus. For this reason, the student orders an online motorcycle taxi through the application. When order, the online motorcycle taxi is in the position s = 2t^2 + 2t + 4, where t is in units of time and s in meters. a. Determine the average velocity of movement of the online motorcycle taxi at 3 minute intervals up to 5 minutes. b. Determine the time when the instantaneous velocity of the online motorcycle taxi is exactly the same as average velocity.
