Suppose you walk for hours at
miles per hour and then canoe
for hours at miles per hour,
covering a total distance of miles.
(a) Write a constraint equation that relates the
time spent walking and canoeing to the total distance
covered.
help (equations)
(b) If you only walk and do not canoe, how much time
do you spend walking?
= hours help (numbers)
(c) If you only canoe and do not walk, how much time
do you spend canoeing?
= hours help (numbers)
(d) Find a solution to your equation in part (a) that
has spends some time canoeing and some time walking.
= hours help (numbers)
= hours help (numbers)
(e) On a piece of paper, sketch a graph your equation
in part (a) and mark your solutions from parts (b)-(d)
on your graph.
Which graph A-D in the figure best resembles your graph?
