If on the first half of the distance the speed is x km/h, in the second one it will be x + 2 km/h.The distances taken with speed 2.30/60.x km and 2.20/60.(x + 2)km and by condition they are equal. From the equation: 2.30/60.x = 2.20/60.(x +2) we get x = 28km/hFor the distance between the two towns we find 2.2.20/60.28 = 140 km.
