Two cyclists ride towards each other. One of them, having an initial speed v01 = 5.4 km/h, descends from the mountain, accelerating with an acceleration a1 = 0.2 m/s2; the other, having an initial speed v02 = 18 km/h, rises uphill slowly with an acceleration a2 = - 0.2 m/s2. After what time will they meet if the distance between them at the initial moment is x0 = 195 m?
