Given distance=360 km. 

$\frac{360}{x} - \frac{360}{5x} = 1 \ \\ </strong></p><p></p><p><strong>[tex] \frac{360}{x} - \frac{360}{5x} = 1 \ \\ \\ \ \: \frac{[ 360x+1800−360x]}{x(x + 5)} = 1 \\ \\ {x}^{2} +5x−1800=0 \\ {x}^{2} +45x−40x−1800=0 \\ x(x+45)−40(x+45)=0 \\ (x−40)(x+45)=0 \\ x=40,−45$

The speed of the train is 40 km/hr.
