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.

Kelvin did not skied without falling more than twice as long as anyone else in his family.

Step-by-step explanation:

The inequality representing the event where Kelvin skied without falling more than twice as long as anyone else in his family is:

Here 223 is the time for Kelvin.

Kelvin skied without falling more than twice as long as Lori.

Kelvin skied without falling less than twice as long as Vanessa.

Kelvin skied without falling less than twice as long as Devon.

Kelvin skied without falling less than twice as long as Celia.

Kelvin skied without falling less than twice as long as Arnold.

Thus, Kelvin did not skied without falling more than twice as long as anyone else in his family.

d is the correct answer
