The amount of time it takes for an ice cube to melt varies inversely to the

air temperature, in degrees. At 70°F the ice will melt in 20 min. How long
vill it take the ice to melt if the temperature is 85°F?

Answer:

Time goes down to 16.47 min

Explanation:

Formula

Time to melt = k / Temperature (I doubt it is this simple)

Givens

Temp = 70

Time = 20

k =

Solution

20 = k / 70 Multiply both sides by 70

20*70 = k

k = 1400

Problem

What happens when Temp = 85?

Time = k / Temp

Time = 1400 / 85

Time = 16.47 Min
