more than 20 miles in total.

The inequality 2.4s + 16.16 > 20 and this graph represent the relationship between
the hours of swimming, s, the hours of biking, h, 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 inequałty for the time constraints (using the hours of swimming s and the
hours of bikingh as your variables) to represent Mai's last statement, "...I think triathlon
athletes generally train for no more than 2 hours a day."
