hey hey!
I'm stuck on the 3rd part (part c) of a problem. Here it is:
Now, I have part a) which I solved to be as...
T=D/S, thus,
T₁= x/8
T₂= y/10
These are the answers to Part A, and they are correct and I understand this part.
I, too, have Part b) in which...
S=D/T, where
D = x+y
T = x/8+y/10
Hence, S = x+y / (x/8+y/10)
S = 80(x+y)/10x+8y
This too, I understand and have a correct answer to.
HOWEVER, with part c) this is my attempt so far...
Naturally, there is no solution to this attempt. I'm confident that this is meant to be a simultaneous equation kind of question, it's just that my actual equations seem to be off. What am I doing wrong?
Any help would be appreciated! <3
