what answers did you get?

Answer 5

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

Answer 6

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

Answer 7

hence 44 and 38

Answer 8

Answer 9

42-35 = 7 difference wups

Answer 10

but i think i multiplied wrong

Answer 11

im working it again to check

Answer 12

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
