A truck is traveling along a road at a speed of x/2 feet per second, when the driver notices some cattle on the road ahead. It takes him 2 seconds before he applies the brakes, and he applies them for a period of x/5 seconds until the truck comes to a complete stop. The truck travels 120 feet from when he first noticed the cattle until it comes to a complete stop, and during that time its average speed is x/4 feet per second. What is the original speed of the truck in feet per second?
