Step 1:
Pick a friend or family member to be the character of your word problem. This friend or family member may do one of the following:
Drive a boat or Drive a jet ski
Step 2:
Select a current speed of the water in mph.
Step 3:
Select the number of hours (be reasonable please) that your friend or family member drove the boat or jets ski against the current speed you chose in step 2.
Step 4:
Select the number of hours that your friend or family member made the same trip with the current (this should be a smaller number, as your friend or family member will be traveling with the current).
Step 5:
Write out the word problem you created and calculate how fast your friend or family member was traveling in still water. Round your answer to the nearest mph.

:
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
