Show answer & explanation
Correct answer: B
Answer: 1320 km
Let the distance between the two trains be d km.
Relative speed = 50 + 60 = 110 km/h.
Time until meeting = d / 110 hours.
Distance traveled by the first train = 50 × d / 110 = 5d/11.
Distance traveled by the second train = 60 × d / 110 = 6d/11.
Given their difference is 120 km: (6d/11) − (5d/11) = d/11 = 120.
Therefore d = 120 × 11 = 1320 km.
Hence the distance between the two trains is 1320 km.
