x is time

there was distance is constant

distance=speed*time

speed1*time1=speed2*time2

50×(x+15)/60=36×(x+50)/60

50×(x+15)=36(x+50)
50x+750=36x+1800
14x=1050
x=75

train reach on 75min or 1h 15min

if speed is 50 kmph distance= 50*(90/60)
=75 km

speed=75*4/5=60kmph

train should travel 60kmph to reach on time
