An explosion at an oil rig in the ocean causes an elliptical oil slick to spread on the surface of the water. The slick is a constant 10 inches thick. After several days, when the major axis of the slick is 10 miles long and the minor axis is 0.3 miles wide, it is determined that its length is increasing at the rate of 20 feet per hour, and its width is increasing at the rate of 6 feet per hour. At what rate (in cubic feet per hour) is oil flowing from the site of the rig at that time?
