Answer : Option A
Explanation :
Let the length of each train be x metres.
Then, distance covered = 2x metres.
Relative speed = (46 - 36) km/hr
| = | \([10 *\frac { 5 } { 18} ]\) | m/sec | ||
| = | \([\frac { 25 } {9 } ]\) | m/sec | |
 |
\( \frac { 2X } { 36 } \)=\(\frac { 25 } {9 } \) | ||
2x = 100
x = 50.
