Answer

Explanation:

Step1: Locate 60 - degree mark

Find the 60 - degree mark on the temperature axis of the graph.

Step2: Determine corresponding time

Draw a horizontal line from the 60 - degree mark until it intersects the heating - curve. Then draw a vertical line down to the time axis. The intersection on the time axis is approximately 3.5 minutes.

Answer:

C. 3.5 minutes
