The space shuttle travels at 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to rea
ch Saturn from earth. Show your work, and convert your standard number to scientific notation. In my problem the Saturns distance from the sun is: 1,424,000,000 KM
and earths distance from the sun is: 149,600,000
Well, if the radius is 10, then the circumference is What's the unit? Either way, 22 rev. per minute means each minute you go by units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed! So, what's the unit for the radius?
