Question

Kelly is on a four-person relay team. The team's total time for its last race was 41.37 seconds. Giselle ran her part in 9.36 seconds. Sarah took 9.71 seconds to run her part of the race, and Aliyah ran her part in 10.57 seconds. How long did Kelly take to run her portion of the race?

Answer 1

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
