A tourist travels from point \(A\) to point \(B\) in 1 hour and 56 minutes. The route from \(A\) to \(B\) first goes uphill, then on flat terrain, and finally downhill. What is the length of the flat terrain if the tourist's speed downhill is 6 km/h, uphill is 4 km/h, and on flat terrain is 5 km/h, and the total distance between \(A\) and \(B\) is \(x\) km? The distances uphill and on flat terrain are both whole numbers of kilometers.
