Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.
Answer:
25 minutes 42 seconds
Step-by-step explanation:
The tub will fill at the rate of ...
2.25 gal/min - 0.50 gal/min = 1.75 gal/min
It will take ...
45 gal/(1.75 gal/min) ≈ 25.714 min
for the tub to fill.
You can shower for about 25 minutes 42 seconds.
