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 and this graph represent the relationship between the hours of swimming, s, the hours of biking, b, 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.
