Total Distance = 365

Distance covered by A in 1 hour (From 10 AM to 11 AM) = 65

Remaining distance = 365 - 65 => 300

The relative speed of the trains to cover the remaining distance = 65 + 35 => 100 Km/hr

Time taken to cover = 300/100 => 3 hours

Meeting Time = 11 AM + 3 => 2 PM

Speeds Ratio = 65 : 35 => 13: 7

Distance from B when meet = 7/20 x 300 => 105
