Step-by-step explanation:
What kind of evil school are you going to?
If I am getting this right, the answer is 1. I think it’s asking what number plus itself plus four = 6. It says,”equal to the sum of the number 6” which I guess is just 6.
So I believe the answer is 1
Recall your d = rt, distance = rate * time.
b = speed rate of the boat.
c = speed rate of the current.
keeping in mind that, as the boat goes Upstream, against the current, it's speed is not "b", but is really " b - c ", because the current is subtracting speed from it.
likewise, when the boat is going Downstream, because is going with the current, is really going faster at " b + c ".

what is the speed of the boat? well, 61 + c = b.
Rules for adding: if the bases are the same you can add them, and subtracting happens in a fraction
