At 11:00am a car (1) leaves city "A" at a constant rate of 60 mi/hr toward city "B". AT the same time a second car (2) leaves city "A" at the constant rate of 50 mi/hr. The distance between cities A and B is 220miles and a highway used by the two cars connects these cities. At what time will the two cars cross eachother?
I think it will be at three tweenty because it will take car (1) will get in the middle of the cities in 4hrs. and car two will get three in 4hrs. 40min. so I added the two together and divided by two and got 3:20 p.m.
