Agroup of runners complete a 26.2 mile marathon in 3.4 hours. the distance between the start and finish lines is 12.2 miles. what was the average velocity for the run?

Explanation:

As we know that the total path length of the Marathon is given as

while the straight distance between start and finish lines is given as

so here we can say that the displacement is the straight line distance between initial and final position which is 12.2 miles

so it is given as

now the average velocity is defined as the ratio of displacement and time

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
