You can put this solution on YOUR website!
Let +d+ = his distance from the start
+d+-+90+ = his distance from the finish
given:
+d+%2B+%28+d+-+90+%29+=+500+
+2d+-+90+=+500+
+2d+=+590+
+d+=+295+
The driver has traveled 295 miles
check:
+d+-+90+=+295+-+90+
+d+-+90+=+205+
and
+d+%2B+%28+d+-+90+%29+=+500+
+295+%2B+205+=+500+
+500+=+500+
OK
