Draw a diagram, assume that the horse is initially at the back end of the train.

Then suppose there is a distance x at which both the horse and train meet. Form two equations , using speed=distance/time for the horse and the train. Solve the equations simultaneously by eliminating the distance x and you should end up with an equation that can be solved for t.

Use distance travelled by train=x and distance travelled by horse= 0.1+x (the 0.1 comes from the fact that the train is 100m long hence 0.1 km long, which is the extra distance the horse must travel).

As an alternative method.

The horse is travelling 56-50 = 6 km/hr faster than the train. So, the question becomes how long does it take to go 100m at 6km/hr?

you should probably change 6 km/hr to 6000m/hr & then into m/min...
