Answer:
The answer to this is 34 minutes and 50 seconds.
Explanation:
First, I multiplied 23 x 2 = 46 because I wanted to see how much minutes it could be in 20 minutes.
Then, I got the answer by getting the median.
23 - 46
the median of that is 34.5. Therefore, the expected time for 15 laps is 34 minutes and 50 seconds.
Hope this Helped!!!!
