Let the speed of the train be x km/h
360/x
=>(360/x+5) + 1
=>360(x+5) = (360+x+5)x
=>360x+1800 = 360x++5x
=>+5x-1800=0
By solving this equation the value of x is 40
Therefore the speed will be 40km/h
please say thanks and mark as best if it helped u

Distance = 360 km
Let the speed of the train be u  km/h
be the time taken to complete the journey be t₁ hr
so
distance/speed = time
so     360/u = t₁  ............  ( i )

2nd case

the speed of the train (u + 5) km/h
so time taken  = t₁ - 1 hr

so 360/(u + 5) = t₁ - 1

substituting ( i ) in the equation

(cancelling the -1)

(doing the middle term factor)

so u = - 45 and 40
so speed can't be negative so the the speed of the train is 40 km/hr
