So 1 hour=60 min.,
So 10/1*60/1=600 min. That means 10 hours = 600 min.,
Then add the 39 min. to this equation= 639 min.,
Then you solve for the seconds, 24/1*1/60=0.4,
So 24 seconds is 0.4 (40%) of a minute,
Then it mean that it would take 639.4 minutes for Saturn to make a full rotation.
Hope This helps!!!

If the difference is always -4.5, then it is always -4.5 times something, so that it changes -4.5 ever 1 number. This means that our equation is y=-4.5x. From there, we can add any constant, as it will not change the difference. I will leave that up to you to pick, so the equation is y=-4.5x+C, where C is any real number.
Hope this helps!
