Answer: 48m2 + 56m
Step-by-step explanation:
About 400 marbles. You simply set up a proportion and solve it as I did in the photo attached.
Constant of proportionality?
I can find the rate of change
ok, so find first hose rate of change
gallons/minue=318/58=159gal/29min
y=159/29x for first hose
2nd hose
50% faster
times 3/2
477/58=2nd hose
constant of poroprotinality
y=kx
assuming y=amount and x is the time
add the rates
159/29+477/58=795/58=13.7
so the new one would be
y=13.7x
constant is 13.7
