At what time will the two trains meet each other? (a) 5 am on the next day (b) 2 am on the next day (c) 5 pm on the next day (d) 2 pm on the next day |

Answer» (a) 5 am on the next day Distance covered by train A before train B leaves Ludhiana = 60 × 3 = 180 km Relative speed = (72 – 60) km/hr = 12 km/hr ∴ Time taken to cross each other = \(\frac{180}{12}\) hrs = 15 hrs ∴ Required time = 2 pm + 15 hrs = 5 am on the next day. |
