The speed of the car is 70km / h from a to B which is 360km away. Suppose the travel time of the car is t (H), and the distance from B is s (km) The vehicle is driven from a to B with a speed of 70km / h and a distance of 360km. Suppose that the travel time of the vehicle is t (H) and the distance to B is s (km). (1) the function of s with respect to t is written;
