Weegy: If Philadelphia and Pittsburgh are 305 miles apart, it will take 2 hours 15 minutes for Rich and Michelle to meet.
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
