Answer: The answers is Monday - one-fourth, Wednesday - six-eight and Friday - one-sixth.
Step-by-step explanation: Given in the question that Mason walked on Monday, Wednesday, and Friday with distances six-eights mile, one-fourth mile, and one-sixth mile. Also, he did not walk the farthest on Monday and he walked less on Friday than Monday. We are to find the distance he walk each day.
The ascending order of the distances travelled by Mason is
six-eights mile < one-fourth mile < one-sixth mile.
On Monday, Mason did not walk farthest and shortest, so Monday will be in the middle. Since Friday's distance is less than that of Monday, so Friday will be shortest and hence Wednesday will be farthest.
So, the days in ascending order are
Wednesday < Monday < Friday.
Thus, Monday - one-fourth, Wednesday - six-eight and Friday - one-sixth.
