Jack is filling his new six person hot tub with a water hose. After 58 minutes, his hot tub has 318 gallons water. His hot tub holds 1,360 gallons of water. He adds another water hose that flows 50% faster. Find the constant of proportionality for the flow rate of the two water hoses combined? (round to nearest tenth)

A) 6.9

B) 8.2

C) 13.7

D) 16.4

Elaine · Answer 1

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
