Two trains are moving towards each other on parallel tracks, both going at a constant rate of 60km/h. A passenger sitting in one of the trains noticed that the other train passed him completely in six seconds. What is the length of passing train in meters?

I really need help on this

Respuesta :

Answer:

200 m

Step-by-step explanation:

[tex]v = 60 km/h \times\frac{1000m}{1km}\times\frac{1h}{3600sec}}=\frac{60}{3.6}m/s[/tex]

For the passenger, the other train moves at a rate of 2v

Time t = 6 sec

The length = (2v) x t = [tex]2\times\frac{60}{3.6}\times 6=200 m[/tex]
