Two trains move towards each other. The first at a speed of 36 km / h, the second at 54 km / h. The passenger on the first train notices that the second train passes by him for 6 seconds. How long is the second train?
So, to solve this problem, we will use a special formula, which is used in such cases.
What we are looking for is called L.
It is found using this very formula:
L = (speed of the first + speed of the second) * number of seconds / number of seconds per hour.
We substitute everything and consider:
L = (54 + 36) * 6/3600 = 0.15. This is measured in kilometers.
We translate into meters.
It turns out 150 meters.
This value is the desired one. Simply put, we solved this problem correctly.
