Answer:

Correct Answer: C

Solution:

  • Let the trains meet after x h of 5 am. So, time taken by train B is $ (x-2),h. $ Speed of train A = 62 km/h Speed of train B = 59 km/h Total distance covered = 827 km According to the question, $ 62x+59,(x-2)=827 $

$ \Rightarrow $ $ 62x+59x-118=827 $

$ \Rightarrow $ $ 121x=827+118 $

$ \Rightarrow $ $ 121x=945 $

$ \Rightarrow $ $ x=\frac{945}{121}=7,h,48\min ,35,s $ Thus, the trains will meet after 7 h 48 min 35 s of 5 am i.e. at 12: 48: 35 pm.
