Interceptor is a simple game. You are given the position and the velocity vector of a target. Your objective is to shoot it down. You are equipped with a single missile located at the position [0,0][0,0]. The missile fires straight up, with the velocity vector [0,4][0,4]. You need to select the time when the missile must be launched in order to intercept the target. The launch time is always an integer. If you select the correct time, the target will get destroyed.(Set up a linear system with 2 equations and 2 variables）
