TRAIN         SPEED      TIME          DISTANCE
A              r-10      190/(r-10)      190
B              r         240/r           240


190%2F%28r-10%29=240%2Fr
Solve for r and evaluate r-10.

Train B travels 50 miles farther than train A, at a speed that is 10 mph faster than train A. That means the trains have been traveling for 50/10=5 hours.

So the speed of the faster train is 240/5 = 48 mph and the speed of the slower train is 190/5=38 mph.
