Answer:
To solve this problem, we need to first convert all of the distances to a common denominator so that we can compare them. We can do this by multiplying each fraction by a suitable value to obtain a fraction with a common denominator.
For example, to compare 2 1/6 miles to 9/4 miles, we can multiply the first fraction by 4/4 and the second fraction by 6/6 to obtain the following:
2 1/6 miles = (24 + 14)/(64) = 8/24 miles
9/4 miles = (96)/(4*6) = 27/24 miles
We can do the same thing to compare 25/12 miles to the other two fractions:
25/12 miles = (252)/(122) = 50/24 miles
Now that all of the fractions have a common denominator, we can easily compare them and determine that Dirk walked the most, at a distance of 50/24 miles. Therefore, Dusty must have walked the least distance, which is 8/24 miles.
So the answer is that Dusty walked 8/24 miles.
