A triangular catchment has an area of 2.5 km² and an average slope of 5 %. The length of the main watercourse (the longest flow path) is denoted by \(L\) metres, and the base of the triangle is twice this length. Using the Kirpich formula \( T_c = 0.0195\,L^{0.77}\,S^{-0.385}\) (where \(S\) is the slope expressed as a decimal), calculate the time of concentration \(T_c\) in minutes, rounded to the nearest minute.
