Travel time: The time T , in hours, required to drive 100 miles is a function of the average speed s, in miles per hour. The formula is

a. Make a graph T versus s covering speeds up to 70 miles per hour.

b. Calculate T (25) and explain in practical terms what your answer means.

c. Explain in practical terms the behavior of the graph near the pole at s = 0.
