After 2.5 hours, how fast is the distance between the boats increasing? C! A. 1:89 kilometers per hour C! E. 21:\"39 kilometers per hour C\" (3- 31.339 kilometers per hour 0 D. 41:39 kilometers per hour 0 E. sass kilometers per hour A triangular prism, with bases consisting of equilateral triangles of side length s, has height h and a volume of 250. If the surface area of the prism includes the areas of all the sides and the bases, what value of s minimizes the surface area of the prism?
