kevin took his pontoon boat out for a leisurely sail.
kevin planned to sail a total of 36 miles in six hours.
during the first two hours of the trip kevin had smooth sailing.
however, for the remainder of the trip kevin hit rough waters and his rate slowed by three miles per hour.
how fast did kevin sail during each part of the trip?
:
find the normal speed; speed = dist/time
s = 36/6
s = 6 mph in smooth water
then
(6-3) = 3 mph in rough waters
