An athlete runs a distance of 1500m in the following manner. (i) Starting from rest, he accelerates himself uniformly at `2ms^(-2)` till he covers a distance of 900m. (ii) He, then runs the remaining distance of 600m at the uniform speed developed. Calculate the time taken by the athlete to cover the two parts of the distance covered. Also find the time, when he is at the centre of the track.
