Two trains of length L = 500 m each, moving along parallel tracks in the same direction. The speed of the first v¹ = 70 km / h, the speed of the second v² = 90 km / h. At some point in time, the 2 “heads” of the trains are equal. How long will it take for the second train to completely overtake the first?
The second train overtakes the first by 20 km / h. In order for him to completely overtake the first, it will take time during which a distance equal to the length of one train of 500 m is covered at a speed of 20 km / h:
S = v * t, t = S / v = 500 m / (20,000 m / 3600 s) = 90 s.
Answer: the second train will take 90 seconds to overtake the first train.
