Let distance travelled by train ‘A’ at the time of meet = ‘x’ km So, distance travelled by train ‘B’ at the time of meet = ‘x + 130’ km According to question; x + x + 130 = 184 => 2x = 54 => x = 27 Distance travelled by train ‘A’ in 9 hours = 27 km Speed of train ‘A’ = 27/9 = 3 km/h Distance travelled by train ‘A’ in 12 hours = 12 × 3 = 36 km
