<span>4 hours after they leave Houston.
Easiest way to solve this problem is to first calculate the relative velocities of the two buses. Since they're traveling in opposite directions, you simply need to add their respective velocities to see what the relative velocity is between them.
55 mi/h + 45 mi/h = 100 mi/h
That means that the buses will increase their distance apart from each other by 100 miles for every hour that they travel. So divide 400 miles by 100 miles/hour
400 miles / 100 miles/hour = 4 hours.
So 4 hours after the buses start moving, they will be 400 miles apart from each other.</span>
X^2 +14x -8 / x-3
= x + 17 with a remainder of 43
See attached picture for solution.
A valid proportion would be 3/4=21/28.
You would multiply both the 3 & 4 is 3/4 by 7 to get 21/28.
Hope this helps!
