A helium balloon gets a small tear and helium starts escaping the balloon at a constant rate. A full balloon contains 2144 cubic inches of helium. After 3 minutes, 480 cubic inches have escaped the balloon. Let V(t) be the volume of helium in the balloon, in cubic inches, t minutes after the tear occurs. How fast is the helium escaping the balloon? Indicate units.
