You can put this solution on YOUR website! Kathy bicyces 6/km faster than Javier. In the same time it takes Javier to bicycle 48 km, Kathy can bicycle 66 km. How fast does each bicyclist travel?
**
let x=Javier's speed
x+6=Kathy's speed
Travel time=distance/speed (same for both)
48/x=66/(x+6)
48(x+6)=66x
48x+288=66x
18x=288
x=16
x+6=22
..
ans:
Javier's speed=16 km/hr
Kathy's speed=22 km/hr
