Thank you very much guys! I got a 10 on my final review!!
5 = 60/(x - 4)
Yes, you need to solve for b because the question is asking for the boat's speed in still water: in other words, what boat's speed would be if there were no current at all. The question isn't asking for the speed of the current (so your answer was not correct).
The answer will be in metres per minute.
What are you not too sure of? The two problems are similar, and I did almost all of question 4 for you. Just apply the concept speed = distance / time.

Do you mean this one:
multiply by 100 to remove the decimals
In a word problem, I was taught to find out what I must calculate and call that x.
