You forgot to ask the actual question

2. anonymous

i did, but i typed it wrong and deleted it.

3. anonymous

speed of train a? speed of train b? I keep getting different answers

5. anonymous

speed*hrs = 220 and (speed-6)*hrs = 190 btw

6. anonymous

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

7. anonymous

hence 44 and 38

8. anonymous

once i got 42 and 35

9. anonymous

42-35 = 7 difference wups

10. anonymous

but i think i multiplied wrong

11. anonymous

im working it again to check

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
