The train travels at a speed of 20 m / s, and another train is moving towards it on the next track at a speed of 36 km / h. How long will the trains pass each other if the length of the first train is 900m, and the second is 600m?
Given: oncoming traffic; V1 (speed of the first train) = 20 m / s; V2 (speed of the oncoming train) = 36 km / h (in SI V2 = 10 m / s); L1 (length of the first train) = 900 m; L2 (length of the oncoming train) = 600 m.
To calculate the travel time of given trains past each other, we apply the formula: t = S / V1.2 = (L1 + L2) / (V1 + V2).
Calculation: t = (900 + 600) / (20 + 10) = 1500/30 = 50 s.
Answer: The specified trains will pass each other in 50 seconds.
