You can put this solution on YOUR website!
Let +h+ = her time for the whole trip
+h+-+5+ = her time for the 2nd part of the trip
--------------------
Let +d+ = her distance in miles for 2nd part of the trip
+d+=+50%2A%28+h+-+5+%29+
--------------------
Her average speed for the whole trip is:
[ total distance ] / [ total time ]
+f%28h%29+=+%28+300+%2B+50%2A%28+h+-+5+%29+%29+%2F+h+
+f%28h%29+=+%28+300+%2B+50h+-+250+%29+%2F+h+
+f%28h%29+=+%28+50h+%2B+50+%29+%2F+h+
+f%28h%29+=+50+%2B+50%2Fh+
