stem a leaf plot look it up
so (Σ8, 12, 15, 18, 18, 20, 21, 23, 23, 23, 27)/12
(20 + 33 + 38 + 44 + 46 +27)/12
(91 + 117)/12
208/12

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
<h3>What was Ryashkina's average walking rate?</h3>
Rate or speed is expressed as distance walked or traveled per unit time.
R = s/t
Given the data in the question;
- Distance covered s = 10,000m
- Time elapsed t = 41 minutes 56.23 seconds
- Rate r = ?
First convert 41 minutes to seconds.
⇒ 41min = ( 41 × 60 )s = 2460sec
Now, Elapsed time t = 2460s + 56.23s = 2516.23 second
Next, we determine the rate.
R = s / t
R = 10000m / 2516.23 s
R = 3.97m/s
Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
