the speed of a passenger train is 6 mph faster than the speed of a freight train. The passenger train travels 330 miles in the same time it takes the freight train to travel 300 miles.Find the speed of each train.

1 answer

speed of freigh --- x
speed of passenger ---- x+6

time for passenger to go 330 miles = 330/(x+6) hrs
time for freight train to go 300 miles = 300/x hrs
but the times are the same

330/(x+6) = 300/x
330x = 300x + 1800
30x = 1800
x = 60

state the conclusion
