Question 1110725: Problem Page Two buses leave towns 865km apart at the same time and travel toward each other. One bus travels 17 /kmh slower than the other. If they meet in 5 hours, what is the rate of each bus? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Problem Page Two buses leave towns 865km apart at the same time and travel toward each other. One bus travels 17 /kmh slower than the other. If they meet in 5 hours, what is the rate of each bus?
-----
slower bus DATA:
rate = r km/hr ; time = 5 hrs ; dist = 5r km
--------------------
faster bus DATA:
rate = r+17 km/hr ; time = 5 hrs ; dist = 5(r+17) km
----------------------
5r + 5(r+17) = 865
10r + 85 = 865
10r = 780
rate = 78 km/hr (rate of slower car)
---
r+17 = 93 km/hr (rate of faster car)
