How long does it take you to get to the other side of town? How
long does it take to get to the other side of the country? If you
were planning a road trip from New York City to Los Angeles, how
long would it take? How would your trip change if you flew instead?
When you plan a trip or vacation, it is useful to first estimate
your travel time. Travel time depends on the vehicle you use, how
fast you travel, the route you take, and even the terrain. For example,
driving over rugged mountains can take longer than driving over
flat farmland. With this information, you can plan your trip so
you arrive at your final destination on time. What's the fastest
way to get from one place to another? Is flying always better than
driving? What would you encounter along the way that could change
your travel time? Form a hypothesis about what is the fastest form
of travel.
