Rich is driving from Philadelphia to Pittsburgh at 70 mph and Michelle is driving from Pittsburgh to Philadelphia at 65 mph. If
nignag [31]
The answer is C. 2 hours and 15 minutes. Please refer to the attached document to see the image for better understanding of solution.

Philadelphia = Point A
Pittsburgh = Point B
X = distance traveled by Michelle
(305-X) = distance traveled by Rich

The general formula used is:

distance = velocity(time)
s = v(t)

Assigning values gives 2 equations:

For Michelle: X = 65(t)
For Rich: (305-X) = 70(t)

Substituting both equations gives:

X = 146.852 miles
t = 2.26 hours or approximately 2 hours and 15 minutes

Solve for w, x, and y. Show your work.
sveta [45]

First of all, the left triangle is an equilateral triangle. Which means that all the interior angles are 60 degrees.

4w=60

w=15

Then all 3 sides are equal thus we can set up equation 3x-y=4y then simplify,

3x=5y

Going to the triangle on the right its isosceles we can set up equation 2x+50=180

2x=130

x=75

Substitute this back into equation above 3x=5y

5y=3*75

y=45

Therefore

x=75

y=45

w=15

Done!
