To solve for the time it takes to travel a certain distance at a certain speed, use the formula,
time = distance / speed
Given that the entire journey takes four hours, add up the time it takes David to row upstream with that of him travelling downstream. This is mathematically represented as,
total time = time upstream + time downstream
4 = 3/(x - 1) + 3/(x +1)
Solving for x in the equation gives 2. Thus, David's speed in still water is 2 miles per hour.
We need to know where the A’ B’ C’ triangle is now located on the graph, can you reply with the coordinates?
Answer: of the burgers were well done
Step-by-step explanation:
Firstly, we are told that a total of 50 burgers were served at Kayla's Burgers, this represents the .

-----
-----
Then:
This means that of the burgers were well done
One hundred forty and ninth five thousand forty six
First pool: 21 liters per min so to get 3100 gone do 3100 divided by 21 which equals 147
Second pool: 33 liters per min and you have 3472 divided 33 = 105
