A Red Cross helicopter takes off from headquarters and flies 115 km in the direction 195° from North. It drops off some relief supplies, then flies 135 km at 350° from North to pick up three medics. If the helicoper then heads directly back to headquarters, find the distance and direction (rounded to one decimal place) it should fly. The direction should be in degrees from north.
