:
Mortimer pedals his paddle boat up the stream to visit Minnie the Moocher in 2 hrs
After a disgusting visit, he heads down stream, and was glad to be be home in 1 hr.
the speed of the current was 2 mph
:
Let s = his pedal speed in still water
:
write a dist equation; dist = time * speed
:
Upstream dist = downstream dist
2(s-2) = 1(s+2)
2s - 4 = s + 2
2s -s = 2 + 4
s = 6 mph is his speed in still water

:
Confirm the solution by finding the distance, they should be equal
2(6-2) = 8 mi
1(6+2) = 8 mi
