If you travel at a constant speed(rate), the distance you travel varies directly with time.  

If you travel 182 miles in 3.5 hours, how far will you travel at the same constant speed in 5 hours?

d = (r)(t)

The driving time between 2 specific locations varies inversely with the average driving speed(rate).  The driving distance between Chicago and Minneapolis is about 400 miles.
