Determine the maximum bending moment, Physics

The weightless simply supported beam below has a VDL of P61kN/m, a point load of P62 kN and a UDL of P63 kN/m as shown.  Determine the vertical reaction force at A the maximum bending moment on the beam, and the closest distance from A to where the Shear force is zero and to the point of contra flexure, all rounded 2 DP. These answers are worth 4 points each.
