Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

What was Ryashkina's average walking rate?​

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.
