Both concentrated and distributed load based problem

A two wire DC distributor AB, 500m long is fed at A at 220V and loads of 40A, 60A are tapped off from C and D which are at a distance of 200m, 350m from the point A respectively. The distributor is also loaded uniformly at the rate of 0.2 A/m. If the resistance of distributor per meter (go and return) is 0.0002 ohms, calculate voltage at point C and point B.
