You and a friend are hiking and find yourselves near the top of a waterfall. There is a path to hike down that takes 1.4 miles to reach the bottom safely and go swimming. There is also a path that is 1.1 miles down to a great place to eat lunch. Your friend wants to stay at the top of the waterfall and fly his drone overhead to take pictures from the sky. A drone is a flying robot that can be remotely controlled with computer software or technology. Draw a vertical number line to help you answer the questions.
