<PRE><B>Question 514292</B>
Two cars started from the same point and traveled in opposite directions.
One traveled at half the speed of the other.
After 5 hours they were 600 km apart.
What is the speed of the faster car?
------
Slow car DATA:
rate = r ; time = 5 hrs ; distance = r*t = 5r km
---
Fast car DATA:
rate = 2r ; time = 5 hrs ; distance = 2r*5 km
---
Equation:
distance + distance = 600 km
5r + 10r = 600
15r = 600
r = 40 km/hr (speed of the sloper car)
