Answer 1

Follow the 5 steps below to complete this problem. (4 points)

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
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.

Answer 2

My mom debbie is driving the jet ski
The current speed is 8mph
She drove for 1 hour upstream to get to the other side of the lake
traveling back with the current took her 50 min.

Answer 3

While on a camping trip my mom Debbie decided to rent a Jet Ski and go for a ride. She wanted to go from one end of the lake to the other side then back to where she started. It took her an hour to get across the lake traveling against the current going 8mph. She knows the jet ski has to be turned back in by noon and its 11:10am already. How fast will she need to go to make it in time.

Answer 4

For these questions a drawing might be more helpful. You have your current, going at 8mph, and you know that if you are traveling \(\color{blue}{with}\) the current that you are moving at a speed of the water plus the speed of the Jet-Ski, for 50min. Using directional arrows can help you decide what operation is necessary and what unknowns you have.
