Elaine is planning a triathlon in her city. The triathlon will consist of three distinct sections, as described below.
Section 1: A swim across a part of Sunset Lake
Section 2: A bicycle ride through the new city park
Section 3: A run through downtown that ends at City Hall
The mayor of the city asks Elaine to follow these criteria: 1. Have a course that the elite athletes should be able to finish in 2 hours.
2. Have the swimming portion of the triathlon be one fifth the distance of the run.
3. Have the entire triathlon cover a distance of 28 miles.
Elaine does some research on top triathlon finish times. She finds that, on average, the elite athletes are able to swim about 4 mi/h, bicycle about 20 mi/h, and run about 10 mi/h. Elaine needs to determine a triathlon course based on these rates.
