During the pre-algebra challenge I'm posed the question: "An alien rocketship is traveling at a speed of 2,500,000 feet per minute. At this speed, how many miles will it travel in 1 second? Round to the nearest thousandth." Upon incorrectly answering it, I'm suggested to review the one unit I still haven't completed to satisfy the Pre-Algebra goal (Simplifying Radicals) but has nothing to do with the question
