A) 82 m |
B) 50 m |
C) 80 m |
D) 72 m |
B) 50 m |
Let the length of each train be x m.
Relative speed = 46 - 36 = 10 km/h
= \( \Large \frac{10 \times 5}{18} \) m/s = \( \Large \frac{25}{9} \) m/s
\( \Large \frac{Sum \ of \ length \ of \ train}{Relative \ speed \ of \ train} = Time \ taken \)
Therefore, \( \Large \frac{2x}{\frac{25}{9}} = 36 => 2x = \frac{36 \times 25}{9} = 100 \)
Therefore, x = 50 m
