Mark wants to set the record for most consecutive ropes jumped.  The record is 54,000.  He can jump 3 times a second.  How many hours would he need to jump rope?
He can jump 3*60=<T>multiply(3, 60)=180 times per minute
So he can jump 180*60=<T>multiply(180, 60)=10800 per hour
So it would take him 54,000/10,800=<T>divide(54000, 10800)=5.0 hours
