141438 A motor-bike starts from rest, attains a velocity of \(10 \mathrm{~m} / \mathrm{s}\) with an acceleration of \(0.5 \mathrm{~m} / \mathrm{s}^{2}\), travels \(10 \mathrm{~km}\) with this uniform velocity and then comes to halt with a uniform deceleration of \(0.2 \mathrm{~m} / \mathrm{s}^{2}\). The total time of travel is
