Solving an Inverse Variation Application: Time for Ice to Melt
Apply the problem-solving strategy for inverse variation to calculate the time required for ice to melt. The problem states that the number of hours it takes for ice to melt, , varies inversely with the air temperature, . Therefore, the general formula is . Given that a block of ice melts in hours when the temperature is degrees Celsius, substitute these values to determine the constant of variation: , which means . The specific equation relating time and temperature is . To find the hours it would take for the same block of ice to melt if the temperature was degrees, substitute into the equation: , which simplifies to or . The ice would melt in hours.

As an industrial facility manager, you are evaluating the cooling efficiency of large ice blocks used in a temperature-controlled process. You know from previous specifications that the melting time in hours () varies inversely with the ambient temperature (). During a test run at 65 degrees Celsius, an ice block melted in 2 hours. You need to project the melting time if the process temperature increases to 78 degrees Celsius. Recall the standard problem-solving strategy for inverse variation and arrange the following steps in the correct chronological order to solve this problem.
