You can put this solution on YOUR website! The speed of a cargo train is 14kph slower than the passenger train. If the passenger train travels 120 km in the time it takes the cargo train to travel 99 km, find the speed of each train. (Show your Solution)
...
Passenger train speed = xmph
Cargo train speed = x-14 kmph
..
Passanger train distance = 120 km
cargo train distance = 99 km
..
time cargo = time passenger
t=d/r
120(x-14)=99x
120x-1680=99x
120-99x=1680
21x=1680
/21
x= 1680/21
x= 80 kmph,,, speed of passenger train.
speed of cargo train = 80 -14 = 64 kmph
