You get in bike north 5 miles and then east 4 miles in 83 minutes. What was your average velocity in miles per hour?

please answer

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
