A truck driver has a shipment of apples to deliver to a destination 550 away. The trip usually takes him 10.0 . Today he finds himself daydreaming and realizes 100 into his trip that that he is running 30.0 later than his usual pace at this point. At what speed must he drive for the remainder of the trip to complete the trip in the usual amount of time?
