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:


Assigning values gives 2 equations:
For Michelle:

For Rich:

Substituting both equations gives:
X = 146.852 miles
t = 2.26 hours or approximately 2 hours and 15 minutes
Answer:
3.20 per yard because there are 36inches in a yard 36×0.5=5.40
$42.50 divided by 4 is 10.625
Than rounding that up to the nearest hundreds which is the number 2, the total is $10.63.
Answer:frfr it made hard
