Dana has 6 hours to spend training for an uncoming race. if she runs at a speed of 9 mph and walks back at a speed of 3 mph, how lond should she plan to spend walking back

Let w = the walking time

the total time is given as 1 hr, therefore (1-w) = running time

Walking dist and running dist is the same

Write a distance equation: dist = speed * time

3w = 9 (1-w)

3w = 9 - 9w

3w + 9w = 9

12w = 9

w = 9/12 = 3/4 hrs walking back

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
