Shane Love is Kayaking in the St. Lawrence River. He can paddle 4.7 miles per hour with the current and 3.4 miles per hour against the current. Find the speed of the kayak in still water and the current.
..
let x=speed of kayak in still water
let c=speed of current
..
with current: x+c=4.7
against current x-c=3.4
add equations eliminating c
2x=8.1
x=4.05
c=4.7-x=4.7-4.05=.65
..
ans:
speed of kayak in still water=4.05 mph
speed of current=.65 mph
