Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. If the faster train passes the slower train in 36 seconds,what is the length of each train?	Choose one:  A) 88  B) 70  C) 62  D) 50  E) 54
Explanation:   Assume the length of each train = x   Total distance covered for overtaking the slower train = x+x = 2x   Relative speed = 46-36=

<output>10</output>
10km/hr= (10×10)/36 = 100/36 m/s   Time = 36 seconds   2x/ (100/36) = 36   =&gt; (2x × 36 )/100 = 36   =&gt; x = 50 meter   Answer: Option 50
