SOLUTION: The time, t, it takes for an ice cube to melt is inversely proportional to the temperature of the water it is in. If it takes an ice cube 2.5 minutes to melt in 70 degree F water,

Question 288755: The time, t, it takes for an ice cube to melt is inversely proportional to the temperature of the water it is in. If it takes an ice cube 2.5 minutes to melt in 70 degree F water, how long will it take an ice cube of the same size to melt in 50 degree water?

y=k/x
2.5=k/70
2.5*70=k
175=k
y=175/50=7/2=3.5 minutes

The best answer is insufficient data.
70 F is not 1.4 times 50 F
Any calculations that multiply temperature have to use "absolute zero" as reference.
--------------
70F = 21.11C
50F = 10C
That makes the ratio 2.11 instead of 1.4. Now what?
