.
Let d be the distance under the question.


The "time" equation is


d%2F5 - d%2F15 = 1%2F6,


saying that the difference of times spent is 1%2F6 of an hour, i.e. 10 minutes.


To solve the equation, multiply both sides by 30. You will get


6d - 2d = 5,

4d = 5,

d = 5%2F4 miles = 1.25 miles.    ANSWER
