The question is the following: "An alien rocketship is traveling at a speed of 0.034 miles per second. At this speed, how many inches will it travel in 1 hour? Round to the nearest thousandth." I did the math and the solution was 7,755,264 inches per hour. It was then asked to round to the nearest thousend which would be 7,755,000. But that answer was shown to me as wrong, when I tried the exact amount, it was right.
