Answer:
![1.8](https://tex.z-dn.net/?f=1.8)
Step-by-step explanation:
Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:
![T\propto \frac{1}{H}](https://tex.z-dn.net/?f=T%5Cpropto%20%5Cfrac%7B1%7D%7BH%7D)
Convert 5 minutes to seconds:
![5\cdot 60=300\:\mathrm{s}](https://tex.z-dn.net/?f=5%5Ccdot%2060%3D300%5C%3A%5Cmathrm%7Bs%7D)
Therefore, from the initial data given (When H=6, T=90), the new time is
larger. Therefore, H must be
times <em>smaller </em>for them to be inversely proportional.
![H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}](https://tex.z-dn.net/?f=H%3D%5Cfrac%7B6%7D%7B3%5Cfrac%7B1%7D%7B3%7D%7D%3D%5Cboxed%7B1.8%7D)
