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 = 550 => 2x = 420 => x = 210 Distance travelled by train ‘A’ in 14 hours = 210 km Speed of train ‘A’ = 210/14 = 15 km/h Distance travelled by train ‘A’ in 7 hours = 7 × 15 = 105 km
