Final answer:
Kendra's speed while moving up the stairs in her house is calculated by dividing the distance of 10.7 meters by the time of 26.8 seconds, yielding a speed of approximately 0.399 m/s.
Step-by-step explanation:
Kendra moves up the stairs in her house with the task of calculating her speed. Kendra's movement took 26.8 seconds, and we are given the distance as 10.7 meters. To find her speed, we use the formula:
Speed = Distance ÷ Time
We convert the time from seconds to minutes or the distance from meters to kilometers if necessary, but in this case, since time is given in seconds, we'll keep the distance in meters for consistency. We calculate her speed as follows:
Speed = 10.7 meters ÷ 26.8 seconds = 0.399 meters per second (m/s)
Therefore, Kendra's speed while ascending the stairs quietly is approximately 0.399 m/s.
