Question 775258: An Airplane leaves Kennedy Airport in New York headed for Los Angeles at a speed of 550 miles per hour. Another airplane leaves Los Angeles an hour later headed for Kennedy airport, flying at a speed of 600 miles. If the two planes are 2375 miles apart, when will the two planes pass each other? I am looking to find a point slope equation.

You can think of this as one plane standing still
and the other one approaching at the sum of their
speeds.
Let +t+ = time in hours until they pass each other
-----------
+2375+=+%28+550+%2B+600+%29%2At+
+2375+=+1150t+
+t+=+2375+%2F+1150+
+t+=+2.0652+
+.0652%2A60+=+3.913+
They will pass each other in 2 hrs 4 min
