Chapter 14, Problem 3PP

Many Global Positioning Satellite (GPS) units can record waypoints. The waypoint marks the coordinates of a location on a map along with a timestamp. Consider a GPS unit that stores waypoints in terms of an (X, Y) coordinate on a map together with a timestamp t that records the number of seconds that have elapsed since the unit was turned on. Write a program that allows the user to enter as many waypoints as desired, storing each waypoint in an ArrayList, where each waypoint is represented by a class that you design. Each waypoint represents a successive sample point during a hike along some route. The coordinates should be input as doubles, and the timestamp as an integer. Have your program compute the total distance

traveled and the average speed in miles per hour. Use the map scaling factor of $1=0.1$ miles. For example, if the only two waypoints are $\left(\text{X}=\text{1,Y}=\text{1,T}=\text{0}\right)\text{ and }\left(\text{X}=\text{2,Y}=\text{1,T}=\text{3600}\right)\text{,}$ then the hiker traveled a distance of 0.1 miles in 3,600 seconds, or 0.1 miles per hour.
