Question

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H , applied to the pot. When H = 6 , T = 180 . What must the cooker setting be if it takes 4 minutes to boil the water?

Answer 1

4.5

Explanation:

Constant of proportionality = 6 x 180 = 1080

4 minutes = 60 x 4 = 240 seconds

H = 1080/240

H = 108/24

H = 18/4

H = 4.5
