The rate for Mars to orbit the Sun is 15 Miles Per Second. First we multiply 15 and 60 to get to Miles Per Minute which is 900. Then there are 60 min in one hour so you multiply 60 by 900 to get 54000 for Miles Per Hour. Now since there are 24 hours in a day you multiply 54000 by 24 to get 1296000 Miles Per Day. So the answer is 1296000 Miles in One Day.
