Question 464077: Kathy bicycles 5km/h faster than Javier. In the same time it takes Javier to bicycle 54 km, Kathy can bicycle 69 km. How fast does each bicyclist travel?
Javier travels _____km/h.
Kathy travels ______km/h. Answer by htmentor(1343) (Show Source):
You can put this solution on YOUR website! Let x = Javier's speed
Then x+5 = Kathy's speed
Since t = d/v, and the times are the same, we can write
54/x = 69/(x+5)
Solve for x:
54(x+5) = 69x
15x = 270
x = 18
So Javier's speed is 18 km/h, Kathy's speed is 23 km/h
