<PRE><B>Question 1021748</B>
The combined speed of the trains is:
50km/17min=50km/0.279hr=179.21km/hr
.
S=speed of slower train; F=speed of faster train=S+8km/hr
.
S+F=179.21km/hr 
S+(S+8km/hr)=179.21km/hr
2S=171.21km/hr
S=85.6km/hr
.
F=S+8km/hr=85.6km/hr+8km/hr=93.6km/hr
.
ANSWER: The rate of the slower train was 85.6 km/hr and 
the rate of the faster train was 93.6 km/hr.
