Question 341233
 two cars leave the same location and travel in opposite directions. One car's speed is 50/mph, while the other's speed is 55/mph. At what time are the cars 273 miles apart?
---------------------
They are separating at a rate of 50+55 = 105 mph
---------------------
time = distance/rate
---
time = 273/105 = 2.6 hrs = 2 hr 36 minutes
