Question 1097761: From point A, a car traveling at 50mph starts toward a point B 500 miles away. Two hours later a second car from B traveling at 30 mph starts toward A from B. When will they meet? Answer by htmentor(1343) (Show Source):
You can put this solution on YOUR website! When car B starts out, car A has been traveling for 2 hours at 50 mph.
So the distance remaining is 500 - 50*2 = 400 miles
Their relative speed is 50 - -30 = 80 mph
The time required to cover 400 miles at a relative speed of 80 mph is
400 miles/80 miles/hr = 5 hours
Thus they will meet 7 hours after A starts driving.
