A Hyundai Santa Fe travels a 1.30km levelled road from Bonifacio roundabout to City Lights Hotel in a minimum time of 45.60seconds. Given that the car accelerates and decelerates at 2.53 m/s², which starts from rest at the roundabout and coming to a stop at the Hotel, determine the maximum speed (in kph) and the time (in seconds) it travel at this speed. Assume time for acceleration and deceleration are egual.
