Question 881716: Nikki drive 20km/hr faster than Alice. In the same time that Alice drives 225km, Nikki drives 325km. Find the speed of each car.
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! The difference in speed is 20kmh
The difference in distance is 100km (325-225)
100/20 = 5 hours
If Alice drives 225 in 5 hours, she is traveling at 225/5, or 45kmh
If Nikki drives 325 in 5 hours, she is traveling at 325/5, or 65kmh
