Ann went on a 10 hour bicycle trip. The graph models the relationship between the time and the total distance traveled by Ann. The table shows selected points on the graph. T=0,1,4,7,10 d(t)=0,3,5,5,10 draw a graph of anns speed in mph in terms of the time in hours.
between 0 and 1 hour Ann went 3 miles per hour
between 1 hour and 4 hours, Ann went 2 miles (5-3) so 2 miles /3 hours = .67 mph
between 4 hours and 7 hours Ann went zero miles (5-5) so zero miles/hour (lunch break?)
between 7 ours and 10 hours (3 hours) Ann went 5 miles (10-5) so 5/3 = 1.67 mph
