A car travels a certain distance from town A to town B at the speed of 42 km/h and from town B to town A at a speed of 48 km/h. What is the average speed of the car?

Two towns are at a distance of 240 km from each other. A motorist takes 8 hours to cover the distance if he travels at a speed of V_(0) km/h from town A to an intermediate town C, and then continues on his way with an acceleration of x km//hr^(2) . He needs the same time to cover the whole distance if he travels from A to C at V_(0) km/h and from C to B at V_(1) km/h or from A to C at V_(1) km/h from C to B at V_(0) km/h. Find V_(0) if the acceleration 'x' is double V_(0) in magnitude and V_(0) ne V_(1) .
