A triathlon athlete swims at an average rate 2.4 miles per hour, and bikes at an average rate of 16.1 miles per
hour. At the end of one training session, she has swum
and biked more than 20 miles in total.
The inequality 2.4x + 16.ly > 20 and this graph
represent the relationship between the hours of
swimming, x, the hours of biking, y, and the total
distance the athlete could have traveled in miles.
Mai said, "I'm not sure the graph is right. For example,
the point (10,3) is in the shaded region, but it's not
realistic for an athlete to swim for 10 hours and bike for
3 hours in a training session! I think triathlon athletes
generally train for no more than 2 hours a day."
Write an inequality to represent Mai's last statement.
