our friend chloe H. asked us how many times could you fly around the world in a spaceship in one day. It turms out its a lot satellite the floating pieces of metal that sand phone called and videos to us fly at 17,000 miles and hour. So they fly around earth in just an hour and hour and a half. But at heese speeds we have a new problem space junk. some of these satellites don't work anymore but there is no way to bring them back down. There are also floating leftover pieces from rocket boosters tools dropped during astronanut walks and so on. Nowthese things are starting to crash into each other If you'er up there doing a space walk grabb some garbage to help us clean up. If you have 4 pieces of space junk and 1 of them breaks in half how many pieces do you have now. 5 pieces. If you've made 9 trips around earth so far today what number is your next trip. The 10th. How many more tips after that can you make today it you can make 16 trips in total. 6 more trips. If you start your orbit at 3:30 pm and the trips takes 1/12 hours at what time will you finish at 5:00 pm. If there are 40 pieces of space junk in your 16 trips today you scoop up 3 pieces can you catch them all. yes you'll be able to catch 48 pieces. if you start orbiting earth today(May 24)and make 16 junk collecting trips each day on what date will you make your 100th orbit. On may 30 you finish 16 trips today and another 80 trips 5 days atter today which is May 29 that brings you to 96 trips so the 100th trips happens on May 30. from called book bedtime math. https://mionasblog.blogspot.com/2011/09/this-friday-watch-out-for-satellite.html
