Question 326398: 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 a.m. 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 to try and track her down and tell her the good news.
Riding at a breezy 15 miles per hour, after how many hours on the scooter will her father catch up to her?

If she went 10 mph for 2 hours, then she has gone 20 miles. The scooter goes 5 mph faster, so how long for something going 5 mph to cover 20 miles? Of course this whole scenario is predicated on the assumption that she keeps going away from the house for as long as it takes her father to catch her, which means that she will have to ride all the way back home. PETA needs to sue the constructor of this problem for animal cruelty since this is about 3 to 5 times the distance a horse should be able to go in a day -- particularly since 10 mph is a fast trot.
