Two sailboats are traveling along the same path away from a dock, beginning from different locations at the
same time. John's boat begins 30 miles from the dock and
is 50 miles from the dock after 5 hours. The distance of
Roberta's boat from the dock is represented by the
function y = 5x + 25, where x represents time and y
represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled
more quickly?
