Answer:
50 (mph) = rate of passenger train
Step-by-step explanation:
Let the rate of the freight train = R
Let the rate of the passenger train be R + 30
The freight train has been traveling for 2 + 3 = 5 hours
And the passenger train has been traveling for 3 hours
And they have traveled the same distance when the passenger train overtakes the freight train
So using rate * time = distance we have that
R(5) = (R + 20) 3 simplify
5R = 3R + 60 subtract 3R from both sides
2R = 60 divide both sides by 2
R = 30 (mph) = rate of freight train
R + 20 = 50 (mph) = rate of passenger train

Hope This Helps!!!
Answer:
A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636
as a fraction it would be 36/99, divide both numbers by 9 to get 4/11
B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
as a fraction that would be 33/90 , divide both by 3 to get 11/30
C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25
