because if they work together it will be 9 hours slower than Kelsey's time alone.
not sure if correct
X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Hypotenuse or C (x) can be found with the equation

After solving you get about 6.32
6.32 about the same as
Using cross multiply and divide the equation looks like so 46/115 next to x/100 to get an answer of 40%
