A young equestrian loved to ride her horse all day long, dreaming of the day she would ride in the Kentucky Derby. One day in early April, she left home at

10:00 am and rode her stallion at a nice, steady 10 miles per hour away from

her house. At noon a call came in from the Derby saying she was in! Her

father immediately jumped on his scooter and rides at a breezy 15 miles per

hour to try and track her down and tell her the good news.

On what scale would you measure the number of minutes the father must

ride his scooter before catching up to his daughter?
