Question 636898: Rosie and Katie left school at the same time, traveling in the opposite directions. At the end of an hour, Katie had driven twice as far as Rosie, and they were 24 miles apart. How far had each driven? Answer by graphmatics(170) (Show Source):
You can put this solution on YOUR website! Let r be The distance Rosie traveled in one hour. Let k be the distance Katie traveled in one hour. Then
k=2*r
k+r=24
Put the expression for k from equation one into equation two:
2*r+r=24
3*r=24
r=24/3
r=8 So
k=16
