You can put this solution on YOUR website! Ryan drives 20 MPH faster than Allicia. In the same time that Allicia drives 225km, Ryan drives 325km. Find the speed of each car
let x= Speed of Allicia's car
x+20=Speed of Ryan's car
travel time=distance/speed
225/x=325/(x+20)
325x=225x+4500
100x=4500
x=45
x+20=65
Speed of Allicia's car=45 mph
Speed of Ryan's car=65 mph
