Question 1137306: Team Awesome starts hiking up from base camp which is located at 4400 feet at a steady rate of 600 feet/hour. At the same time, team cool, which has hiked up earlier, leaves the top of the peak at 8900 feet and starts hiking down at a steady rate of 900 feet/hour. After how many hours do the two teams pass each other ?

You can put this solution on YOUR website!
Then distance between them is +8900+-+4400+=+4500+ ft
Add their rates of climbing
+600+%2B+900+=+1500+ ft/hr
Let +t+ = time in hrs until they pass each other
+4500+=+1500%2At+
+t+=+3+ hrs
-----------------------
check:
+d%5B1%5D+=+600%2A3+
+d%5B1%5D+=+1800+ ft
and
+d%5B2%5D+=+900%2A3+
+d%5B2%5D+=+2700+ ft
------------------------
+1800+%2B+2700+=+4500+ ft
OK
