Inverse variation occurs in the real world. Some real world examples occur when catering, driving, and the speed ice melts.

Example: The time it takes a block of ice to melt varies inversely as the temperature. If it takes 4 hours for a 2 square inch block of ice to melt at a temperature of 70°, find the time, h, it would take a 2 square inch block to melt at a temperature of 40°.

interactive exercise, assistance may be required Move the variables to the correct location to form the general inverse variation equation for the ice block.

Fill in the values and find the constant k.
