Difference between there speed = 21 - 16 = 5 kmph.
When they meet difference between distance covered = 60 km.
Faster train takes time to maintain this distance gap = 60/5 = 12 hours.
It means after 12 hours, they meet each other.
So distance between Kohlapur and Mumbai,
16 * 12 + 21 * 12 = 192 + 252 = 444 km.
