In the first 45 minutes, train A is able to travel 100 kmh * (3/4) h = 75 km.
The relative speed of the second train to the first train is 36 kmh. Thus we need to find the time that the second train will take to cover that distance:
D = s*t
75 = 36kmh * t ==> t = 75/36 h
Now we need to find the distance traveled in that amount of time:
D = s*t
D = 136kmh * (75/36)h
D = 283.33 km
