Question 240512: I need to solve the following word problem using the system of linear equations in two variables. The word problem I am having trouble with is:
Traveling with the current, a canoe can go 48 miles in 4 hours. traveling against the current, it takes 6 hours to go the same distance. find the speed of the canoe in still water.
I came up with the following linear equations:
12=x+y for speed of canoe with current
8=x-y for speed of canoe against current
I solved for each variable and came up with x=10, y=2.
My question is which one is the correct answer for finding the speed of the canoe in still water? My thought is it is x=10.
Please help

Question 241646: Ok. So I am currenty in Algebra 1 and we're learning distance problems.
We were taught using the box method (maybe your familiar?)That looks something like this:
Rate x Time = Disance
Abby
Jake
I'm rather confused with a certain problem:
Ferris and Julia jog around a circular track that is 500 meters long. Julia's rate is 250 meters per minute, while Ferris's rate is only 230 meters per minute. In how many minutes will Julia be a full lap ahead?
Perhaps if you understand the box method, you could show me how to put the information in that format? Or if you think you know an easier way (less computations or hassle) that would be great!
Thank you and have a good Thanksgiving! (It's never too early! :D)
