In the science lab, Will is testing the freezing point of a substance, which should be −24 °C. He is changing the temperature at a rate of −3 °C per minute, starting at 0 °C. Question 1

Part A

Write an inequality for the time t before the temperature reaches the freezing point.

Drag the number or symbol into each box to correctly complete the inequality.
