During the blasting operation of the mountain construction, it is known that the burning speed of the fuse is $0.5$ centimeters per second, and the speed at which a person runs away is $4$ meters per second. The safe zone is defined as being at a distance of $150$ meters away (including the $150$ meters) from the blasting point.
