    5 hours have gone by, because the trains are 30 miles apart

    Let speed of Train B be x miles/hr Then speed of train A is (x-6) miles/hr it's given that in equal time train A covers 190 miles and train B covers 220 miles so \[ \frac{190}{x-6}=\frac{220}{x}\] or\[190(x)=220(x-6)\] \[190x-220x=-1320\] \[-30x=-1320\] \[x=44\] so spee of train B is 44miles/ hour and train A's speed is 38 miles/hour
