Kelvin went skiing with his family. They kept track of how long they each skied without falling. The table lists the longest time that each family member skied without falling.

Person Time Skied
(seconds)
Kelvin 223
Lori 55
Vanessa 265
Devon 172
Celia 112
Arnold 356
Part A
Kelvin wants to know whether he skied without falling more than twice as long as anyone else in his family. His dad tells him that he can check by using the inequality 2f < 223, where f is the time skied in seconds for each person. Plug the values for the time skied by each person into the inequality to find the answer.
