This is also similar to the other question you posted. Here you have the length of the train and you have to calculate the speed of the train.

I will just cut short the explaination and jump to the solution. you can see the explaination in the other question​.

Let the speed of train be v km/hr.

relative velocity = v - 5

time = length/ speed
10 = (125×18)/{(v-5)×5}

v-5 = 45
v = 50 km/hr
