Respuesta :

Answer: 11.73 seconds

Step-by-step explanation:

To solve the question, we have to add the time used by Giselle, Sarah and Aliyah and then subtract from 41.37 seconds to determine the time used by Kelly. This will be:

= 41.37 - (9.36 + 9.71 + 10.57)

= 41.37 - 29.64

= 11.73 seconds

Kelly used 11.73 seconds
