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
Drive a jet ski
Select a current speed of the water in mph.
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.
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).
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.
I did your first problem. I hope this helps you to get on the right track. Perhaps with that little inspiration you can figure the rest out by yourself?
