Total distance = 440

distance covered by A in 1 hour (From 4 to 5) = 40 Km

Remaining distance between them = 400 Km

Speeds Ratio (A: B) = 2 : 3

Distance covered by A til meeting = 400 x 2/5 => 160 Km

Total Distance covered by A til meeting = 160 + 40 = > 200 Km

Relative Speed to coover the distance = 60 + 40 => 100 Km/hr

Time taken to cover the distance = 400/100 => 4 Hours

Meeting Time = 5 PM + 4 => 9 PM
