Question 1015386: If side A is 4 miles and B is twice as long, how fast would Becca have to ride at a constant speed if she wants to make the trip in 35 minutes? Your answer should be exact and simplified in miles per hour.
(Picure with a triangle - distance of longest side is not given. One side is 4 miles (A) and another is 8 miles (2A). Longer side is the bottom triangle). Looks like below (without 3rd line)

What is "the trip"?
We can help you more easily if you are precise and complete asking your question.

If the triangle is a right triangle the longest side is:
.
longest side=sqrt%284%5E2%2B8%5E2%29=sqrt%2880%29=4sqrt%285%29 miles
.
If "the trip" is once down the longest leg in 35 minutes:
.
%28%284sqrt%285%29mi%29%2F%2835min%29%29%2860min%2F1hr%29=%2848sqrt%285%29%29%2F7 miles per hour
