One passenger train is 190 meters long and the other freight train is 290 meters long. What is the speed ratio between passenger train and freight train 5: 3. When driving in the same direction, the time for two vehicles to cross is 1 minute. Ask them about driving in opposite directions, what is the time for two vehicles to cross?

The speed of passenger car and freight car is 5x, 3x
5x-3x=290+190 x=240
(290 + 190) / (5x + 3x) = 480 / 8x240 = 0.25 points
